Session2:StatusReport–Land,Ocean,andAtmosphereDomainTeams
Land
Koji Kajiwara (Chiba University) spoke about two potential applications of combinedHimawari-8 and GCOM-C data. Firstly, he suggested a drought detection system using aWater Stress Index (WSI) derived using high-frequency Himawari-8 solar radiation timeseries (developed by Dr. Takenaka, JAXA/EORC) in combinationwith GCOM-C land coverdata. Such a system would support early warning of forest fires in the Asian region byobserving dry environmental conditions. The second potential application is hot spotdetectionusinghigh-frequencytimeseriesofthermalinfrareddata.Kajiwara-sanpresenteddemonstrationsoftheseapplications(seepresentationfile).
LuigiRenzullo(CSIRO)presentedanupdateonthelanddomainworkongoinginAustralia,including Land Surface Temperature (LST) retrieval investigations and CSIRO’s work withBeijing Normal University to explore the application of AHI visible channels to infer LeafAreaIndex(LAI)andLeafAngleDistribution(LAD).
AjointprojectbetweenCSIRO(LuigiRenzullo),BOM(LeonMajewski)andCurtinUniversity(PeterFearns)aimstoimplementandevaluateAHILSTretrievalsandassess:performanceagainst LEO instruments (e.g., MODIS, Landsat); and the accuracy required for surfaceenergybalancestudies.GiventhesimilaritybetweenAHIandABI,CSIROhasadoptedtheresearchofDr.YunYueYu(NOAA)andisapplyingrecommendedSplitWindowAlgorithms(SWAs) to Himawari-8 data to assess the required accuracy for generation of certainproducts, in particular evapotranspiration (ET). LST retrievals for Australia have beencomparedwith those fromMODIS, andwhile the results display varying degrees of bias,theyareoverallwellcorrelated.
Luigi closed by outlining some next steps for the LST product development and desiredoutcomes fromtheJapan-Australiacollaboration.TheLSTteamwill investigate theuseofACCESS TCWV, explore alternatives for emissivity (including adapting dynamic land coverclassification approaches), evaluate the inclusion of flux tower data (potentially fromOzFlux,AsiaFlux,Fluxnet),andexplorefurtherapplicationofcloudmasking.Luigiiskeentoprogress collaboration with the Japanese team, noting that the collaboration presents agoodopportunitytocomparemethods,dataandresults.

Nakajima-sanpresentedsomefurtherinformationrelatedtoSGLI(seeslidesfordetails)andclosed by summarising the Himawari-8 products being distributed by JAXA EORC (shownbelow; underlined products are produced regularly and starred productswill be releasedshortly). JAXA’s products can be obtained via FTP following a simple user registrationprocess,see:http://www.eorc.jaxa.jp/ptree/
IanGrant(BOM)spokebrieflyaboutworkongoinginAustraliarelatedtosolarradiationandozone/UV (aerosols will be covered in a dedicated presentation during the hotspot andhaze/aerosol session). While the Bureau’s main focus is applying Himawari-8 data forweather forecasting, there are R&D activities around select non-meteorologicalapplications.
Solar radiation products from Himawari-8 are under development by BOM. The solarradiationschemeimplementedbyBOMreliesontwoseparatesoftwarepackages:GEOCATtoprocessHimawari-8dataandderivecloudproperties(CloudOpticalDepth(COD) isthemost important cloud parameter for solar radiation); and Heliosat-4, which takes cloudpropertiesandancillarydatatomodelsolarradiationatthesurface.BOMhopestoderiveUVmapsfromHimawari-8/AHIdata,andthefollowingparametersarenecessary:

Nakau-san outlined the satellite data sets that JAXA uses/will use to derive fire-relatedproducts,notingthefollowingdependencies:
− Firelocation(CIRC,SGLI,Himawari-8/AHI)− Smoke(GOSAT,GCOM-C)− Firedanger(GSMaP,GCOM-C,GCOM-W)
GSMaP can be used as an input for fire risk index models, and soil water content fromAMSR-2 is also very useful. Modelling is used to derive fire smoke production, smoketransportation and fire danger metrics. CIRC is a key instrument for fire detection, andNakau-sanpresentedsomeresultsandmethodologies.

Ian closed by summarising the approach used for the Bureau’s real-timeHimawari-8/AHISSTproduct.Aregression-basedapproachwasselectedasitisfastandstandalone,howeverit requires training data, which is provided by NOAA-ACSPO VIIRS SST L2P. A number ofmodels/bandshavebeen trialled,andBOMfound thatperformance isonlyweakly linkedto complexity. As such, a simpler model using only the LWIR bands was selected –facilitating day andnight acquisitionswithout discontinuities. Furtherwork is planned, asoutlinedbelow.

Summaries of the two breakout sessions, as presented during theworkshop by Shin-ichiSobue (JAXA) and TimMalthus (CSIRO), are attached in Appendix B and C. The resultingactionsarerecordedinAppendixD,alongwiththosefromtheplenarysession.
Session7:WrapUpShin-ichi Sobue (JAXA) presented a brief summary of the workshop. He noted that bothbreakoutgroups:
− Identifiedgoodopportunitiesforcross-validationofwork;− Notedtheneedtoestablishrelationshipswithusergroups;and,− Shouldassesspotentialcontributionstoexistingframeworks.
Shin-ichinotedthatthehotspotdetectionandhaze/aerosolgrouptookanactiontowriteupasummaryofproductsof interest forcomparison/validation– includingPOCs,targets,etc.andheproposed that theoceancolourandseasurface temperature teamshoulddothesame.
Shin-ichi noted that we will share our progress and a summary of the workshop at theupcoming CEOS SIT Technical Workshop for information. We would like to be able topresent case studies (using existing systems) at the upcoming APRSAF-23 (Manila,November) to report progress and contact stakeholders (for example, the AsianDevelopmentBank, Indonesianauthorities,etc.)andthenfollowupatAPRSAF-24 in2017withspecificdemonstrationsofthesocietalbenefitsofthecollaborationfocusprojects.
We will aim to establish quarterly catch-up teleconferences to keep the communicationlinesopenandtrackprogresswhileweworktowardsthenextGEO-LEOmeeting,tobeheldinAustraliain2017.

APPENDIX C – Hotspot Detection and Haze/Aerosol Monitoring BreakoutSessionSummaryOverall Goal: Provide hotspot and haze/aerosol information derived using GEO and LEOsatellitestousersintheAsia-Pacificregion.It was agreed that the best approach to achieving the overall goal is to identify someachievablefirststepsthatwill:i. Help improve the independent systems being developed on both the Japanese and
Australiansides;and,ii. Facilitatethegenerationofcompellingcasestudiesandexamples,includingofexisting
systems,thatcanbepresentedtootherAsia-Pacificcountriesanddonorbodies(ADB,UNEP,JICA,WorldBank,ASEANFund,AustralianDFAT,APEC)togenerateinterestandinvolvement.

algorithms,etc.)andinformationforthepurposeofsystemvalidation.Itwassuggestedthatastandardiseddataformatformatchinghotspotsbeestablishedinsupport.
− Worktogetherto identifya targetareaforvalidationactivities–preferablywithinthecoverage of AustralianMODIS ground stations. It was suggested thatMODIS hotspotproductsbecomparedwiththosefromHimawari-8(Australianteamtolead)andCIRC(Japaneseteamtolead).
− Identify potential user groups/end users and possible contributions to existingframeworks(inparticularthoserelatedtopublichealth,firemanagement,aviation,etc.)such as AIRCAP (Australian BOM to lead the follow up), UNEP ABC (JAXA to lead thefollowup),andtheAsia-PacificCleanAirPartnership.
− Prepare case studies that demonstrate the potential societal benefits of GEO andintegratedGEO-LEOproducts–incoordinationwithusergroups(e.g.,firemanagersandpublichealthbodies).
− Investigate (together) the integration of local hotspot products into existing smoketransportationmodels(e.g.,fromKyushuUniversity,CSIRO/BOM(MartinCope’swork)).
− Collaborators will communicate their independent validation of aerosol products anddiscussacommonvalidationprotocol(sites,dates,metrics).
− ALOS-2/ISS CIRC data is available for hotspot measurements (however ISS CIRCobservation opportunities are limited). The Australian teamwill provide the Japaneseteamwith advancednoticeof prescribedburnevents (at least 3daysbeforehand) sothatacquisitionscanbecoordinated.
RelevantExistingProgrammesandSystems− Hotspot detection systems (Australian Sentinel Bushfire Monitor, CIRC/GCOM-
C/Himawari-8system(expectedinDecember2016),Indonesiansystems).− AERONET (includes CSIRO AOD data), JAXA Himawari Monitor (aerosol products),
