SMEAR TECHNICAL MEETING 2015

GENERALMaintaining long term measurements as before, focus again in spring measurements (Ecosystem)

HYYTIÄLÄ

IT

New server for raw data replaces atm-raw2 2015/02

New Timo server (Linux CentOS) in active useo Used mainly as disk server, copies data from measurements computers to \\

timo\smear and Helsinki. One can install Matlab to run scripts.

o Readme files describing coying scripts etc. Plase keep diary, what you have changed there

Some very big data producers (e.g. TOFs, Eddys)o Separate disk space for these data (40 Tb)o One in Kumpula (Physics server), one in Hyytiälä (in future atm-raw3)o Access is very limited

Hyytiälä internet connection updated to 500 Mb/s early 2014

New desktop computers installed spring 2014

New data folders should be named without CAPS due properties of Linux Some problems with Matlab scripts The computers of measurement network shouldn't be used to internet surfing

o Not actively updated to new Windows versions Linux should be considered for measurement computers

o We have serial logging programs for Linux Remote access to measurement computers

o VNC from other computers in the measurement networko SSH pipe from other VPNs inside universityo Coogle Chrome remote desktop from wherever

The data flow and connections with FMI still undefinedo Data can be transferred to Cloudo VPN

The data transfer should be organized for both Siikaneva sites (Heikki, Teemu, Risto) Data visualisation for visitors

o New TV-size screen in the main huto Markku, Timo, Jaana and Tuukka scripts?

Data visualisation for duty people

1

All the data collected in UHEL will be open access in futureo It is essential to get users for the collected data also outside our own groupo Meta data very important (how, when, where, WHO)

Could there be new easier, more automatic ways to keep the meta data up to date?

Technicians have big responsibility over thiso Also the data of scientific visitors

o Automatic flagging (channel information) and event (calibrations, instrument changes...) collection of the data should be established ==> person needed?

MAIN STATION

Ecosystem Footprint kaulusten kasvillisuuskartoitus (Nuria Altimir kiinnostunut?). Jokainen kaulus

(54) + valuma-alueen 7 kaulusta käytävä läpi, kuvat otettu 2014 mutta nyt täytyy tehdä paikan päällä (kesä-heinäkuussa). Synkronoi am. biomassainventoinnin kanssa? Kesätyöntekijä?

CH4 N2O kaulukset, kesätyöntekijät Pintakasvillisuuden biomassainventointi elokuussa Hyytiälän footprint-alueella 60

näyteruutua (20 x 20 cm). 1 viikko kasvien keräyksen, erottelun ja kuivauksen kanssa. Coordination with ICOS protocols. (Liisa)

o kesätyöntekijät This year’s tree biomass sampling would be good to make also at the ICOS plots

REA(Radiation)-Tower The tower will not be extended Foundations must be repaired and guys checked Minor disturbances to measurements Single trees can be felled to keep radiation etc. sensors in clear horizon.

o Tree to the south 2 m away from the top Measurements clearly over canopy should be mounted to the mast or the measurement

towero in practise everything can be moved except eddyo future of eddy will be decided later, O3 flux?

Need to have tower inside forest for fluxes, profiles, in-canopy chemistry etc.

Power Uninterruptable power system

o Preliminary plan made by contractoro There is consensus over the needo Board has contacted university administration

Centralised compressed air and vacuum production Main hut area Mink to the cellar

dew point monitoring to compressed air High temperature protection for containers power cut

Meteorology Järvenpää radar to Hyytiälä late Feb- early Mar (postponed to May-June?) 2015. It is a

sea container with a 4.5m antenna on top. Placed to the old ARM site close to the A-house. Help needed from the station personell.

Move the precipitation measurements out from the old (short) FMI container The comparison between the temperature measurements 67.2, 50.4 and 33.6 m is not

good. 50.4m measurement seems to be OK. 8.4m measurement has most likely blower problem.

o Eki will check but also Germans have problems so no point putting too much effort

o SMEAR staff checks 8.4 m blower asap Thies wind 67.2m is broken

o 3D Metek will be installed as replacement Tower T and RH is missing

o new instruments by 30 Aprilo New data connection box needed (serial/ethernet server, power etc.)o Delta Sunshine Sensor will also be connected to this

Gas PTR-TOF spring-summer with FMI (Heidi Hellen) Diagnostics signals to new Nokeval TEI 146i calibrator excess flow sensor should be bought and installed H2O monitor for the H20 generator and dew point sensor installation Horiba mast CO offset in the analog signal shuld be studied. Calibration off in the pressure difference sensors in mast and cuvette lines LI820 removal from the setup NO and NO2 instruments to new tower cottage. Short sampling lines. One instrument

from cuvette setup and one specific instrument coming in Feb 2015. Needs gases and clean air. Pressure regulators (N2, Air) to the new tower cottage.

CI-APITOF continues in the new tower cottage. Scroll to the pump room with UPS. Does someone use the measurements above 67 m from the old Li-Cor profile?

o The old profile could be replaced with a completely new sampling system from the bottom of the mast up to 33.6 m, with couple of new sampling levels for example 1 m and 2 m height? Is there room for this (ICOS EC storage protocol)?

New extended REA tower could also accommodate this

Radiation SpecNet NDVI and PRI sensor installation and monthly cross-calibration maintenance

for at least one year. Measurements starting 2015 or 2016 spring. Location to be decided (Albert Porcar) See separate document.

3

o Location in the tall tower fully OK to decagon peopleo PRI & NDVI, 1 sensor up, 1 sensor down nadir, another off-nadir = 6 sensorso boom etc. special arrangements for installation? How far from the tower

horizontally? Decided in the next few days. Need to be easily dismantled for calibration

o Approx. Monthly calibration on the top of the tower. Jon, Pasi K take care of those. Or Albert

o Decagon datalogger(s)o SDI-12 specs needed to connect to our system. Heikki et al. Direct connection

with Decagon. Converters exist.o Installation first week Marcho The Decagon campaign will continue until at least next winter. We might keep

the sensors or perhaps move to Värriö (calibration?)o OO spectrometer also at some point to the tall tower

Skye PRI sensors should be back in February 2015. Installation by mid-March next to the Skye-NDVI (Albert Porcar)

o PRI back to the mast asap (early March)o Interest to move Skye NDVI also to the tower

The Monitoring-PAM remains in the old phototower where trees can be more easily accessed. Regular maintenance check, data download of the Monitoring PAM has been discontinued during the last years and this can be seen in the data (longer gaps due to snow during winter). If possible, it would be good if the weekly visual check/sensor cleaning could be re-established.

o Data flow will be fixed. o SMEAR staff can also do very quick visual data checko Albert provides some documentation etc.

The data is an international precedent and there are a number of papers on the making with it… (Albert Porcar)

PRITOVOC Campaig campaign does not involve input from SMEAR-II technical Staff. In practice, a Chinese PhD student from Barcelona will be staying in Hyytiälä for two months (mid March-Mid May) and conduct regular leaf-level sampling/measurements in the towers at SMEAR-II. She will be also doing measurements in the Institute. (Albert Porcar)

o OO system should be working during the campaign, Caroline will send new laptop. Albert & Jon calibrate.

Reflected global sensor should be at 67 m for ICOS compatibility, consistency with net radiation and reflected PAR, and old time series. New sensor instead of moving the 125 sensor.

Hukseflux at some point (late summer 2015?). New Sunshine Sensor for total & diffuse PAR should be installed.

o Sensor waiting for installation. New data acquisition box. Deadline 30 April.

Flux New O3 analyser FOS Sextant installation. Tower or mast? Old LOZ has not been in use.

o Monthly filter replacement must be considered when placing the instrumento Mast!

4

COS soil chamber(s) from Open University (UK)/UCLA (USA), and our COS Aerodyne to be installed with them; construction so that Aerodyne is switched to measure air concentration or EC flux then and then. Expected time late June (Helmi)

Subcanopy EC verification. It seems to produce mostly noise. Should we continue or change the site…

o EC system stopped due malfunction with data loggingo New setup needed – if needed – Värriö subcanopy based portable setupo While waiting for responsible researchers' decision the old setup can be

dismantled. Tower Li-Cor waiting for change, could SMEAR staff do it instead of Sigrid travelling to

Hyde for 1 hour job?o Joo.

Photo (Anni Vanhatalo, Juho Aalto) New photo tower in use since spring 2014. In old tower one cuvette still in use. Shoot, soil and stem cuvettes in rotation. Birch has been measured now second year

o Juho and Anni will monitor the data Water accumulation guard for the photo CO2/H20 analyser/sample lines under

construction (Heikki, Petri) PTR-MS will measure from cuvette and mast as before New stem cuvette for exchange and water soluble compounds under design

o Topi Lite cuvette system under design

o In-house design, possible manufacturing of mechanical parts by Topi NO and NOx were taken out (and will stay out) from the cuvette system. One in us in new

tower cottage and one spare. New O3 analyser available for the cuvette. Should be simple to install. Old tower can be taken partly down, but it is needed during summer 2015 by Mari

METAFOR (setm CH4 and N2O). planning will be started for all enclosure upgrades (Anni: dynamic stem enclosure;

Pasi/Juho/Jaana: kevytkyvettisysteemi; Mari/Jukka/Liisa: soil enclosures [for CH4, N2O, CO2]); potentially Topi's workshop could be involved, Heikki? Total revision of the old cuvette system control software and electronics will be planned. Technical details will be figured out once ALL responsible researchers have made their requirements clear (gases, chamber type, number of lines, measuring frequency and closure time etc.)

online GC-MS for enclosure and air VOC concentration measurements. Planning should be started.

The status of LGR measurements (broken connectors, clock setting) nykyisessä kyvettilinjastossa kiinni olevan LGR CO/N2O laserin datavirran

järjestäminen,o Eki will sort this outo Juho will collect the data and save it to Timo

Tree

the stem measurements in new tower still need some input from Heikki/Eki (Teemu Hölttä)

o should be ready during February (very cold weather might postpone to March) spruce stem diameter and sapflow: Annikki's spruce measurements need to carry on,

technical assistance appreciated; Summer workerso Heikki should check the set up

Lämpötilanmittaus (esim. termopari) 3 puusta (2 mäntyä ja koivu) rungon alaosaan noin 1 cm syvyyteen ja versoon/ Teemu Hölttä (Juho & summer workers)

Mittaus loppuu -11 C:ssao Nokeval ongelmao Tilanne tarkastetaan uuden tornin tiedonkeruun osaltao Pt100?o Kyvettien lämpötilamittaukset liittyy tähän

mikrokairaus/Tuula Jyske: kolme näytepuuta, arviolta 15-30 min/kerta. Näytteet tulisi ottaa kahdesti viikossa keväällä. (Pauliina & summer workers)

Dynamax clock should be synchronised with SMEAR time

SOIL pitkäaikaismittaukset pääosin ennallaan Picarro 13CO2 measurement from soil profile will be continued, system works well and

data looks OK (Jukka P).o Water traps should be emptied occasionally

Yhden hukassa olleen mutta sittemmin löytyneen Tohelikammion asentaminen yhdelle Jussin Trenching-plotille

o Whatever plot where the system is easy to install All the 3 electrical ToHeLis in Hyytiälä

o Should be checked and repairedo The one staying in Hyytiälä could be changed to work with compressed airo requires power and setting up data acquisition

Imulysimetrikeräykset 1 päivä kuukaudessa. Kesätyöntekijä CO2-kammiomittaukset manuaalikammioilla joka toinen viikko pimeä ja valomittaukset.

1 päivä joka toinen viikko 14 kaulusta valuma-alueella. Maakammiomittaukset (N2O, CH4). SMEAR II valuma-alueen manuaalikammiot: 2 vk:n

välein (Matti tietää), kesätyöntekijä, MaSa automaattikammio: putkien vaihto ja seuranta. Footprint (METAFOR projekti): mitataan vain ne kammiot, jotka sijaitsevat tutkittavien puiden lähellä, mittauksetsamanaikaisesti runko- ja latvustokyvettimittausten kanssa. Intensiivinen kevät: huhti-toukokuu (mittauksia niin paljon kuin sää sallii ja on mahdollista). Kesätyöntekijä tarve 13.4. alkaen.

Automaattikammioiden toiminnan tarkistus joka viikko. Kesätyöntekijä Sadevesien ja patovesien keräys , suodatus, pH ja johtokykymittaus joka toinen viikko. 2

päivää joka toinen viikko (Sirkan tuuraus). Kesätyöntekijä Sadekeräimien puhdistus joka viikko. Kesätyöntekijä uusia tai kampanjoita (ks tarkempi kuvaus alla)

o Biohiiliprojektio trenching –kokeen mittaukset, nyt uutena DOC,VOC ja N2O & CH4o METAFOR - metaanilähteet ja -nielut (Marin projekti)

Hyytiälä selvittää (Matti)

UUSI PROJEKTI: Jukan Biochar-projektin koealojen perustaminen (aputyövoiman tarve 2 viikkoa).

Kokeeseen tulee Hyytiälään koealoja, joille levitetään puuhiiltä ja tutkitaan sen vaikutusta maan orgaanisen aineen hajoamiseen ja puiden/taimien kasvuun. Kokeeseen tulee lämpötila-antureita, todennäköisesti ruukkutaimia ja maankosteusmittauksia. Sekä maanäytteenottoa. Projektissa työssä 50% työajalla Marjo Palviainen. Help from summer worker will be needed occasionally.

Jussi: trenchingiin liittyen työtä aseman väeltä vaatisi edelliskesän tapaan säännöllinen vuomittaus. Uusi ajatus DOC-mittauksista on hiukan raakile ja juttelemme siitä Miitan ja Annen kanssa ensi viikolla. Imulysimetrimittaus ploteilla voi toteutuessaan vaatia apuja tekniseltä väeltä, ainakin siinä vaiheessa kun pumppuja ja sähköjä pitää vetää alueelle.

o Lainataan valuma-alueen imusysteemiä Trenching-kokeen kammiomittaukset 1 krt kuukaudessa (CO2-, CH4- ja N2O-vuot). CO2 kammiot: 2 vkn välein? (sama työpanos ja –intensiteetti kuin viime vuonna) N2O, CH4 kammiot: 1 krt/kk (max 15-18 kammiota/pv = 3 pv) maan kosteus, CO2 ja N2O/CH4 kammiomittausten yhteydessä.

Kesätyöntekijä/gradulainen. UUTTA: imulysimetrimittaus trenchingeihin asennetuista lysimetreistä. Asiasta

keskusteltu/keskustellaan Anne O:n ja Miitan kanssa. Kerran kuussa? (kytkee trenchingin ja juuristoaktiivisuuden DOC-valuntaan)

kasvillisuuskartoitus trenching-ploteilta (sovittu tehtäväksi Evu Tuittilan kanssa, ei vaatine resursseja)

VOC-mittaus (Mari Mäki); huhti-lokakuussa, trenching ja maaprofiilit sekä pintakasvillisuuden mittaukset, apua tarvitaan kyvettien ym. systeemien tarkistukseen (Juho) ja mahdollisesti ajoittain mittauksiin (kesätyöntekijä)

Miniritsotronit (Heljä-Sisko) Miniritsotroneilla määritetään hienojuurten kasvudynamiikkaa SMEARin männikössä.

Kolmen vuoden aineisto 2012-2014 on valmis ja analysoitu, laskenta talvella 2015. Kuvaamme SMEAR-männikön miniritsotroneja yhtenä päivänä kuukaudessa touko-

lokakuussa myös 2015, liittyen 2012 perustamaamme kasvupaikkagradienttiin Hyden ympäristössä, jossa SMEAR-männikkö on mukana. Emme tarvitse mittauksissa apua.

Rahoitus työhön tulee Suomen Akatemian projektistani. Suunnitteilla on myös aloittaa kasvupaikkagradientilla tarkempi juurten kasvun fenologian seuranta maanalaisen kasvukauden alussa ja lopussa viikoittain samoista putkista (1 pv per viikko touko-kesäkuu ja lokakuu) esikokeena jätetylle NSF-hakemukselle. Mittaaja on vielä auki, voisikohan touko-kesäkuun mittaukset tehdä joku SMEAR-kesätyöntekijä? Voin maksaa palkan tältä osin, siis noin 1 pv viikossa ja opetamme työn.

Voiko kevään työvoimatarpeen yhdistää Metafor-projektin kanssa

Kamera Hydessä helpottaisi työtä (on ollut infralistalla jo vuosikaudet..). Käytimme 2010-2013 Metlalle aikoinaan hankkimaani kameraa. Viime kesänä ja ensi kesänä käytämme Tarton yhteistyökumppaneiltani lainassa olevaa kameraa.

SiliCarbo pii- ja hiilimittaukset maavedestä (Miitta) Keräämme maavettä SMEARII lysimetreistä keväällä ja kesällä sateen jälkeen. Piin ja

hiilen määritykset tehdään pääosin Helsingissä, saatamme tosin Hyden kaasaria muutamille näytteille. Hoidamme näytteenoton itse.

o Kannattaa koordinoida Matin ja Sirkan kanssa ja mahdollisesti yhdistää normaaliin SMEAR näytekeräykseen

ICOS

ATM/meteo Päävirtauslinjoihin lisätään filtterit ennen hiljalleen tukkeutuvia virtausmittareita (1kpl

jo paikallaan) new Rotronic at 33.6 m (Ecosystem)

o Extra logging capacity might be needed Atmospheric pressure measurements are not ICOS (AS) compatible

o Risto will order ICOS compatible pressure sensoro Should be installed to measure pressure outdoors, not inside the cabin (door

closed => pressure changes etc.)o In principle, Eki is strongly against

Generally the data logging frequency should be increased (of ICOS related parameters)o Recommendations 0.1 Hz to 0.03 Hzo Kolari will collect the upgrade list after protocols are final

Could the logging of the “ICOS diagnostics” (flows etc. including p) be moved to Picarro’s integrated computer ==> 1 Nokeval needed

o Should be tested More markings in log books (for instance about installations with instrument serial

numbers, calibrations etc.)o e.g. ICOS concentration data transfer to France hasn’t happened yet since the

serial numbers of meteorological instruments are not knowno Rotronics could be called according to the Physics inventory number

ventilation needed in the basement for gas bottles; maybe also a fan to mix air and minimize the vertical T gradient, so that the bottles don’t need to be horizontally

o Extra fan to the cellar in principle the whole calibration setup (cylinders, regulators, sampling lines) should be

in the same temperature as the instrument which is calibratedo According to test made by Keronen the gas flow from present cal. system is in the

same temperature as the ambient sample air flow The requirements for 0…33.6 m CO2/H2O-profile measurements (storage change flux)

are still openo Picarro measures at 16, 67 and 125 m heights for ICOS ATC needso Independent system or integrated to the old profile measurements (causes need

for rebuild)

Ecosystem 4 soil/biomass plots, 50-70 m distance from the mast. The pits in the catchment area

are not used for ICOS-measurements, at least not as a primary source of datao final planning should be done during 2015 (=”koealojen pyykitys”, exact

locations of instruments in the field, power & data logging etc. etc.)o however implementation mostly during 2016o Nothing done yeto INWIRE tests still ongoingo Some protocols still unfinishedo soil T and humidity from approx. 5 depths up to 1 m deep if possible,

groundwater height if needed (mostly in SW direction)o soil heat fluxo subcanopy PAR, measurements must be synched with the above canopy PAR!

Apogees should be replaced with better sensors (Licor?) Relates to the biomass plots

o litter collectors and litter plotso automatic dendrometerso etc.o there’s going to be quite a lot of traffic at the plots due to vegetation and soil

sampling, some boardwalks are probably neededo inevitably there’s going to be quite a lot of wires going around, although

some things can be done wirelesso Soil chamberso In the beginning measurements are done with “Toheli”, n units neededo For the auxiliary data measured in parallel (T, humidity,?) no big changes

needed in data collection?o Measurements should be done further away from the catchment areao In the future larger chambers should be used (make/order larger ones when

there’s need for new ones, coordinate with the chamber revision)o This year’s biomass sampling would be good to make also at the ICOS plots

Aerosols (Pasi Aalto, Jonathan Duplissy) DMPS, CPC and APS working just fine. DMPS rebuild when we have the time. New Hitu computer installed 2014 New computer to new tower container installed 2014 (PSM, NAIS, DMPS…) New PSM zero system will be installed in the near future ==> better results Jonathan D. is the contact person for PMSs APS was in ACTRIS intercomparison workshop in Leipzig, performing fine New APS program in use starting 12/2014

During 2014 there was a DMPS running at the BAECC field and in the new tower. Those measurements are finished.

Old CPC TSI3022 was changed to new model TSI3775 MAAP, Aetahlometer, Nephelometer, CAPS and PSAP running fine, some inlet changes

done for CAPS 12/2014. MAAP has now a pump with control. New optical inlet dryer under planning/testing, The current design is not sufficient

enough for MAAP, not enough flow capacity. Sampling line should be also simplified, especially for CAPS. The new design might have some capacity problems also, testing this winter in Helsinki. With the new inlet, it might be good idea to move the inlet away from the corner, even if FMI radiation setup will be moved away.

o Might cause a need for bigger compressor SHARP running. Some unstable periods. CCNC running just fine, some program crashes Volatility-DMPS running Impactor sampling will continue.

o How about the data quality. ELPI will continue Tower TwinDMPS (02/2015) Maintenance and improvement of Tower-PSM Container-PSM installed again in near future

o With automatic zero system Ice Nucleation Counter, already this year? ACSM has been working but the data is noisy

o The analyzer of the old C-TOF could be changed to ACSM, probably in Aerodyne

o Everything is open at the moment A new HR-AMS is purchased, coming to Hyytiälä in the future

o To the new Physics container

Ions (Hanna Manninen) NAIS in tower container

o To the shady sideo Inter-comparison in Hitu-huto Timetable unknown

NAIS 14 in Hitu-cottage or in Cessnao To the Helsinki in March

BSMA in REA-cottageo Good results, nice time serieso Copying procedure (computer) should be updated

SIGMA in radiation towero Moisture problemso Works nicely on event dayso Campaign measurements on the field in February

Radioactive radiation (Alessandro Franchini, Xuemeng Chen) Milan radon running fine

10

Data collection should be better integrated to SMEAR II system

Analytical chemists (Kari Hartonen) SPME cuvette measurements with Jaana Bäck Luis will be carrying on the measurements between March and May GC-MS to the new side of the main hut

FMI measurements (Hannele Hakola, Jussi Paatero…) Hg measurements PAH measurements PAH and Hg fallout measurements should be moved to the roof platform of the

the 3 underwater PAR sensors need to be checked. They are in Helsinki now. Eventually to be sent to Licor. They should be put back on the lake possibly in April (Risto, Ivan).

2 or 3 temperature profiles from water, to catch internal waves and thermocline slopes; temperature chains to be installed in May(Anne, Ivan, Risto)

near-bottom thermistor chain and oxygen probes (probably also in May); Arkady Terzhevik from Russia knows (Russian visitors, Anne, Ivan)

Short campaign (one week) at the end of August with Viikki turbulence profiler and the Sally MacIntyre SCAMP (not yet confirmed, depending if Sally is able to come to Finland) (Ivan, Anne, Sally).

One week manual gas sampling under the ice focusing on spatial variability, probably on week 7 (Ivan, Anne, one Russian visitor).

11

Lidar campaign in summer. One Lidar will be installed on the raft. Exact starting date and duration of the campaign to be decided soon, probably in May-June. (Ivan Mammarella and Ewan OConnor)

SiliCarbo (Miitta Rantakari) Määritämme järvivedestä piipitoisuuksia. Näytteet on tarkoitus ottaa samalla, kun

järvestä muutenkin otetaan vesinäytteitä (minulla ei ole Timon listaa, en tiedä mitä siellä sanotaan, mutta synkronoimme näytteenoton). Piimääritykset tehdään Helsingissä. Ainakin heinäkuussa SMEAR kesätyöntekijän apu järvinäytteenotossa olisi tervetullutta.

Asennamme järveen kaksi sedimenttitrappia (samoin kuin viime kesänä). Hoidamme itse näytteenoton. Kuitenkin jos SMEAR kesätyöntekijä heinäkuussa ehtii yhden tai kaksi kertaa vaihtamaan trappien putket, olemme kiitollisia (n. 2h työ/kerta).

SIIKANEVA1 Gill anemometer and 7200 Licor to be installed to make the site more towards ICOS

Class II (Risto)o LI-7000 is down, ref. gas over + other problems? – to be done in Jan 2015

Renovation of the platform and instrument box during the summer/autumn 2015 Automatic chambers, plant chambers (Topi?) New measurement platform (Meronen ?) Dam in the ditch/outlet and flow rates and water concentrations? (Janne R, Eeva-Stiina,

Meronen ?)o Plans still open

4-channel radiometer settings problem, quantization problemo Logger set up problem (Risto, Eki)o Logging could/should be done with PC

buy a spare LGR. (LGR, which model?), just to have a spare instrument. Pekka and later Risto will handle this

o Risto will determine with Timo the old Tprof doesn’t make sense, heavily dampened signal due to moss overgrowth?

o ???? replace the logger, not been configured correctly (quantization problem). Some changes

are needed ---> Pekka will contact Eki. A new logger with larger memory would be also nice (higher measurement frequency for met-data?)

o PC and Nokevall??? check the ch4 prof data with the new sampling settings after 30th Nov by Risto/Tiia

o Timing changed LGR problems

o doesn’t work as of now (21.11.2014)o timelag problemo noise problem (doesn’t seem to affect the calculated fluxes, but still…)o in parts of some raw files, missing values or constant values are loggedo a period when only the CO2 channels were logged, with “-1” written for CH4o maintainance in Helsinki since dec 2014

raw file size is varying; sometimes a few days in a row consist of very short files. Computer/logging issues,Computer changed in Dec2014

reasons for the notably different level of 2012-2013 CH4 fluxes. check the relative change in CO2 fluxes and SEB closure; happened after the anemometer was changed?

needs a new computer - done dec 2014 ICOS INWIRE remote flux measurement setup prototype at Siikaneva1

12

o there is already small tower plus some soil instruments installed in autumno transport from Sweden and installation during first half of Aprilo details to be discussed, one option is van&ship transport to Hyde via

Umeå&Vaasa instead of using commercial transport serviceso fuel cell, 500 l tank, batteries integrated in one box

won’t be used in Siikanevao 2 solar panels about 20 kg each, also need some infrastructureo SMEAR staff take care of the timberwork and on-site transporto technician from Amsterdam will come to Hyde to set up the instrument tower,

his timetable is flexibleo communication uses 3G network, data directly to Amsterdamo setup removed in summer when the summer worker rush is over (late June?)

SIIKANEVA2 floating chambers (“wetland group”) dissolved CO2, dissolved CH4 on ponds (“wetland group”), profiles? isotopes from floating chambers (Vesa Palonen jne.) Siikaneva-2 generator problems (since Sep. 2014), caps in data

o No problems lately

Siikaneva-2: need exact conversion coeffso for METEK, uvw-coeffs known, but NOT Tso for PAR, PAR – coeffs known (Dec 2014)

Measurements should be restarted late March

CAMPAIGNS

Marin METAFOR -projektin työt (maa+puumittauksia):

Tekniset tarpeet ja toiveet

Torni märälle paikalle, jotta pääsemme käsiksi latvuston (koivu erityisesti) metaanipäästöihin. Torni pitäisi asentaa huhtikuun alkuun mennessä, jotta päästään mittaamaan huhtikuussa, ennen kuin lehdet puhkeavat. Tarkoitus olisi saada mitattua 3-6 puuta, erityisesti koivu, manuaalisesti operoitavilla oksakyveteillä (Mari tilaa lisää jo olemassa olevien lisäksi). Näytteiden analyysit tehdään kaasarilla.

13

Mahdollisuuksia:

rakennustelineiden vuokraus rakennusfirmalta

Haapastensyrjän torni?

Mahdollisesti useita eri telinesettejä, jotta pääsemme käsiksi mahdollisimman moneen

koivuun

o Jatketaan suunnittelua maastokäynnillä helmikuussa

Mittausten tueksi sap-flow-mittaukset jokaiseen tutkittavaan puuhun

o min. 3 koivua, 3 kuusta, 3 mäntyä – riippuen miten torni saadaan asetettua

Kysymyksiä:

Sähköistys sap-flow-mittauksia varten, onnistuuko?

o Onnistuu

Loggeri sap-flow-mittauksille, onko vapaita loggereita?

o On

Jos em. sähköt ja loggeri järjestyy, Teemulla on tiedossa hlö (Risto Punkaharjulta), joka

osaa pystyttää mittaukset, ja joka kävi viime vuonna pystyttämässä Annikin mittaukset.

o Teemu Paljakka vastuussa SapFlow neulojen hankinnasta

Aikataulu:

Maalis-huhtikuu: Tornin pystytys märälle alueelle. Tarvitaan teknistä henkilökuntaa avuksi (pari

pv?)

measured at the same time with tree stems/shoot fluxes (April-August?)

Stem chamber measurements (as in 2014)

conducted parallel to shoot and forest floor flux measurements, except semi-wet

site where we don’t have a tower

pine, spruce, birch (as in 2014)

Shoot chamber measurements

wet and dry site

wet site: new scaffold tower, birch and pine trees (3 each if possible, or at

minimum 3 shoot chambers / tree species – even 3 chambers in one tree

individual), in total 6 shoot chambers

dry site: old scaffold tower, 3 pine trees, 3 shoot chambers

Technical assistance needed (March, April-May)

scaffold tower to the wet site (to the place in March?)

sap-flow measurements to trees at the wet site (Teemu responsible)

poles etc. to help fixing shoot cuvettes in the trees at the wet site

Extra workers / summer workers

David from Germany (Aino Korrensalon kautta tuleva harjoittelija?), wants to do a

training period for min. 6 weeks. Needs accommodation

Summer worker, 3 months (13.4.-15.7.) to help in

1) flux measurements (intensively in April-May)

2) vegetation survey (2 weeks in total)

Rebuild of the met towero Simultaneously with renovation of the met measurementso Time table open

Nothing done to improve the station thunder storm security Nothing done to protect the gas instruments serial interfaces from thunder strikes Should we change the thunder storm instructions to avoid long breaks during summer

time?o Present procedure causes caps to the data

Sigrid would like to reinstall webcam to the met towero There is common interest phenology camera(s) installation

Meteorology Temperature and WS gradient not needed and in bad shape. Finish the measurements

o T profile needed for Eddy?

Thies WS/WDIR probe broken. Change that.o FMI will give some old Thieses

Improve the T/RH probe setup at 2m height Is station pressure OK?

o Sensor is inside the hut

Radiation Nothing new. Check all against reference instrument during spring/summer, especially the UV sensors against the new reference sensors.

Gases New NO2 analyser exits, but does not fit to the gas rack

Flux Met Tower EC working fine, no changes Wetness sensor integrated to the measurements.

o Does this mean the same kind of sensor there was in the past? Yes.

Subcanopy EC Li-7500->Li-7200 this spring. No CH4 EC. Conversion of the old Li-7500 to mobile system to be used to verify the subcanopy EC measurements around (for example Hyytiälä)

Tree Puiden pituuskasvu, versomittaukset tornissa joka aamu. Kesätyöntekijät läpimitanmuutokset 2 puussa, working only at the tower, the other tree is not working.

Eki will be given instructions (Teemu Hölttä/Lauri Lindfors) to fix this in spring. Eki has already fixed this?

Photo Measurements with four cuvettes will continue. Station personnel and summer workest

will maintain. Anni Vanhatalo will monitor and maintaino Ladders will not reach the cuvettes in near future. New way to maintain cuvettes

needed. Quality of T and PAR is not good. Differences (some degC) in temperatures between

cuvettes and some noisy thermocouples exist. PAR measurements have some cyclic noise since autumn 2014 .

o Air blower thermostat should be checkedo Eki will instruct the permanent staff

LiCOR mittausten tarkkuus? peräkkäisten mittausten ero suurempi kuin URAS-aikana (LAATU-koodinpätkä tarkistusta varten) Suomeksi: data on siis kohinaista. Kyvettien data, mukaanlukien kohinat, on mukana varrio_data-koodistossa, noita Mathematica-koodeja ei kukaan aikoinaan tuntunut oikeasti käyttävän.

o Ei ole varmuutta onko asiassa todellista ongelmaa. Epäilyn saattaa aiheuttaa mittalaitteiden erilaiset aika-vakiot ja datan laadun valvontaan käytetyn Mathematica koodin ominaisuudet.

compensation still not done right.

Gases PTR-TOF flux measurements late 2015 or early 2016

Flux Checking enclosed-path measurement setup. Particularly heating of the inlet should be

fixed. Problems with the EddyCPC. The TSI3781 water CPC is a bit unreliable and faces

freezing problems during winter time. New box with a new CPC? The EC measurements with TSI OPS were not successful. Some other instrument?

Aerosol PSM running (Lauri Ahonen) Automatic version DMPS rebuild during 2014. CPC is the Airmodus A20. Running fine.

Ions AIS3 for continuous measurements? Unsure due limited amount of available instruments

TREE ANU: Rutiinihuoltoon keväällä kuuluu sapfluxneulojen huolto. Ja niiden vaihto

tarvittaessa (6 kpl) ja läpimitanmuutosanturien huolto, kaikkiaan noin 1,5 työpäivää yhdeltä hengeltä (Janne J). Sapfluksineulojen teon työaikavaateesta ei mulla ole tietoa. Em. toimilla Viikin automaattimittaukset pyörii jos ei tule suurempia laiterikkoja tms.

Tähän saakka on joka vuosi mitattu versonkasvua touko-heinäkuu n. 3 x vkossa, vie noin 10 t viikko. Jatketaanko, en tiedä.

Teemu ja Jukka miettinevät mitä he haluavat mitattavan ja miten se järjestyy. Viikissä ei ole nyt toimivia steadytemp palikoita eikä neuloja eli jos ne halutaan, on rakennettava ja asennettava, tuplannee työaikatarpeen.
