EMEP intensive measurement periodsTo assist the implementation of the EMEP monitoring strategy. The task force of measurement and modelling (TFMM) has recommended conducting co-ordinated intensive measurements between the Level-2 sites (joint EMEP/GAW supersites). Furthermore, cooperation and involvement of research groups with more advanced research activities (i.e. level 3) has been encouraged

Outline of this talkSome main results from the different measurement periodshighlight the interlink with research projectsHighlight the importance of infrastructure project to develop harmonized

methodology and reporting guidelines in Europe

Intensive measurements 2006/2007

Data available from 2006/2007

Chemical speciation comparison

Measurements of organic carbon is much higher than modeled, especially in winter

Indications of problems with official emission estimates

Not complete chemical analysis of measurements in Switzerland

Model suggests that mineral dust can be important in the summer

Lessons learnt from the 1. EMEP IMP• Produced a set of valuable data and new possibilities for

validation of the EMEP model, In particular: • size-distribution and formation rates of HNO3 and coarse nitrate• the diurnal variation of ammonia, EMEP model to be coupled to a

dynamic ammonia emission module• underestimation of EC and OC at southern sites, suggesting that

residential wood burning source is underestimated in winter

• Identified several measurement problems• Lack of mineral dust measurements• Biased measurements for nitrogen and carbonaceous matter• Lack of comparability• No standardized reporting format

Improved in future intensive periods

Intensive periods 2008 and 2009

Sites with AMS measurements in the EUCAARI campaigns 2008/2009

Relative organic source contributions (ME-2 results).

EMEP IMP 2008/2009 - The Carbonaceous Aerosol

Source apportionment of the carbonaceous aerosol by using weekly data on EC, OCp, TCp, levoglucosan and the 14C/12C as input for the statistical method Latin Hypecube Sampling (LHS)

Weekly measurement and centralized laboratories and/or harmonized method (i.e EUSAAR-2)

Relative contribution to the carbonaceous fraction in PM10

Five predefined subcategories/sources.

Elemental and organic carbon from combustion of

biomass (ECbb and OCbb)

fossil fuel sources (ECff and OCff),

organic carbon from natural sources (OCnf).  

Intensive periodes 2012 and 2013June 8 to July 12(7) 2012, and jan/febr 2013 One year measurements with ACSM (from june 2012)High resolution, and extended measurements of aerosols

and its precursors (ACTRIS) while EMEP has a special focus on mineral dust.

A cooperation between • EMEP TFMM (http://www.nilu.no/projects/ccc/tfmm/ • ACTRIS (http://www.actris.net/)• ChArMeX (http://charmex.lsce.ipsl.fr). • EARLINET• Pegasos (http://pegasos.iceht.f orth.gr/

Data quality and quality control• Essential to have harmonized measurements to be

able to do comparison over time and space• Standard operation procedures and reference

methods developed• Regular field and laboratory intercomparison• Reporting guidlines

Monitoring frameworks:Infrastructure projects

Summary The EMEP intensive measurement periods have become an important part of the

monitoring programme Production of high resolution and/or advanced measurement (EUCAARI and ACTRIS). Production of chemical composition data on mineral dust and carbonaceous matter

using comparable field and analytical methodology at a number of regional background sites representative of different European regions

Established reporting guidelines and QA/QC procedures for a range of new components for the EMEP Community (EUSAAR and ACTRIS project central)

Enhanced the cooperation between the research and monitoring communities –win win, co benefit: EMEP benefits from the scientific development and development of reference

methods and reporting Research projects benefits from infrastructure and added value of the data (increased

visibility). Partnership is often a prerequisite to get funding from the Commission Data available at: http://ebas.nilu.no/ Future campaigns are not fixed. Potentially in 2016, though need partnerships
