ProductFamilySpecifications(PFS)
AndreiaSiqueira(GA)presentedthebackgroundofthedevelopmentoftheCARD4LPFS.20+peopleparticipatedineachofthePFSreviewteleconferences,andtherewasgoodengagementfromavarietyofcommunities.Anumberofdifferentchangeshavebeenappliedtoeachdocument.However,somechangeswerethesametoallthreedocuments,suchas:theinclusionofachapterforthedefinitionsandacronymsusedinthetext(e.g.,LST,SBT,ancillarydata);changedwordsundertheguidancesectiontosaythattheproductswillberesampledontoacommongeometricgrid(foragivenproduct)andwouldprovidebaselinedataforfurtherinteroperabilityboththroughtimeandwithotherdatasets.Twomajorsuggestionscameoutoftheteleconferences:splittingthelandsurfacetemperaturePFSintotwocomponents(surfacetemperature,brightnesstemperature)andthedevelopmentofmoreradarPFS(e.g.,interferometricSAR).Alldiscussions,feedback,dates,actions,etc.,arebeingcapturedinanExceltable.TheupdatedPFSdocumentsaswellastheExceltablearekeptintheGoogleDrive.
JonathonRoss(GA)askedwhetherweshouldbeprioritisingtheimplementationphasebeforelookingatmodifyingtheexistingPFS.HeaddedthatPFSinstabilitycouldhamperuptakebydataproviders.

ReferringtotheplannedfurtherrevisionsofthePFS,StevenHosford(ESA/CNES)stressedthatweneedtobeawarethatnotallofCEOSis‘operational’,andweshouldbeconsiderateoftheamountofresourcesavailableforthiswork.
SusanneMecklenburg(ESA)askedwhetheranupdateofallPFSisnecessaryatthisstage,suggestingthatweinsteadfocusonSAR.AkeRosenqvist(JAXA)agreed,suggestingthatupdatesshouldonlytakeplaceasneeded;excessivechangeswillbeadragonresourcesandmakeimplementationmoredifficultfordataproviders.
ItwasagreedthattheplannedannualupdatesofthePFSareunnecessary,howeverweremainopentomakingminorincrementalchangeswhenevernecessary.PFSstabilityisthepriority.
WGCV’sroleintheCARD4Lassessmentprocesswasdiscussed.JonathonRoss(GA)suggested:callingthecurrentPFS‘pre-final’;askingLSI-VCagenciestodopracticeassessmentsforcandidateproducts,recordingtheirprocess;andthenusingtheseinputstoprepareafirstdraftoftheCARD4LAssessmentFramework.WGCVcanthenbeengagedfortheirfeedback.
ItwasagreedthatWGCVshouldbeengagedintheassessmentprocess.
StephenWardstressedtheimportanceofhavingaclearARDstrategytoinformdatausers,providers,andintermediaries(especiallythe‘BigData’hosts),tomakethemawareofwherewe’reat,wherewe’regoing,andpersuadingthemthattheyshouldbeusing/producing/hostingCARD4Lproducts.TheARDstrategyshouldcoverthesepoints,aswellasPRandoutreachtopics.
Summary
− NocomprehensiveupdatestothePFSonanannualbasis–wewantstabilityinthespecifications.− TheSurfaceReflectanceandSurfaceTemperaturePFSareconsideredbaselined;minorclarifications
arepossiblelaterthisyearafterthefirstagenciesgothroughtheassessmentprocess.− LookingforLSI-VCagenciestostartpilotingtheassessmentandproductionprocessoverthecoming
months(e.g.,JAXAonSAR,ESAonSurfaceReflectance,USGSonSurfaceTemperature).AimforresultsbythejointmeetinginSeptember.UsetheseexperiencestodraftanofficialassessmentprocesstosharewithWGCVforreview.
Itwasagreedthatasub-group,ledbyJAXA(TakeoTadono,AkeRosenqvist)andESA(NunoMiranda)shouldbeestablished(seeactionbelow)toseethatthisiscompleted.
