JonathonRoss(GA,CEO)presentedanoverviewofCEOStohelpsetthestage,recallingtheKyotoStatementandthenumerousglobalagendasthatarerelevanttoCEOSanditsagencies.HenotedtheCEOSWorkPlanandthe2017CEOSChairInitiatives.Thetwochairinitiativesbridge thegapbetweenusersanddata.TheFDAad-hocTeam(FDA-AHT) isassessing thestrategic direction for CEOS, and also progressing Pilot activities to inform the strategicdecisions. Bottom-up activities on ARD are vital to the overall success of top-level FDAstrategydiscussionsandotheractivities.

LSI-VCImplementationPlan

In response to action LSI-VC-2-21, Jenn has taken responsibility for updating the LSI-VCImplementationPlan(IP).TheIPisbeingrevisedsothatitbetterreflectsthecurrentdirectionandprioritiesoftheVC,andtoensurethatitisconsistentwiththeCEOSWorkPlan2017-2019.Jennreviewedthedocumentthatshehasmarked-upwithsomesuggestedchanges.Thefollowingpointsfromthediscussionwerenoted:

• JennnotedthefollowingaimfromtheIP:“Promotingsustainedandsystematiccollectionofsatellite-derived landsurface imagingobservationsbysharing informationonfuturemissiondevelopment”.

o Itwas agreed that itwould be helpful to use the CEOSMIMDatabase (MIMDB) togeneratesomecustomtimelinesforLSI-VCpurposes.

o JeffMasek(NASA)notedthatthegapidentificationpotentialofsuchtimelineswouldbehelpful–most importantlyforSAR(asoptical isalreadywellcoveredglobally).DavidJarrett(NASA)supportedtheidea,statingthatgapidentificationshouldbeapriority.

o IvanPetiteville(ESA)stressedtheimportanceofpublicisinganyresults.

It’s unknown when global Landsat Surface Reflectance (SR) products will be availablesystematically(asopposedtobeingprocessedondemand).LCMAPwillproduceproductsforthe continental United States. Adam confirmed that Geoscience Australia (GA) are notproducingLandsatSRproductssystematically.

Adam Lewis (GA) stressed that CARD4L is not meant to cover specialised users orinterferometric applications, and the applicability of a SAR ARD product should not bedismissed.TherearemanynewpotentialusersforbasicapplicationofSAR,e.g.,inforestryandagriculture(riceandcloudyareaobservations,inparticular)thatwouldbenefitgreatlyfromabasic product.Wehave seen this need communicated through consultationswithusers(e.g.,viaSDCG-GFOI,GEOGLAM).

It was suggested that all nomenclature be well defined and consistent with other CEOSdefinitions(e.g.,theuseof‘moderate’whendescribingasensorresolution).

MuSLIandHLS

JeffMasek (NASA)presenteda summaryof twoprojects that arehighly relevant toMRI:Multi-SourceLandImaging(MuSLI)andtheHarmonizedLandsat-Sentineldataset.

MuSLI is a set of research projects, funded through the NASA Land-Cover and Land-UseChange(LCLUC)Program,thatareworkingtoadvancetheuseofmulti-sourceremotesensingdata for land monitoring applications. Each project makes use of multiple, internationaldatasets to achieve their goals, and an emphasis is placed on regional pilot projects andprototype products that can be scaled-up. A new solicitation for 2017 projects has beenreleased,withanincreasedemphasisoncontinental-scaleproducts.

UniversityofQueensland(UQ)Update

Adam Lewis (GA) presented some updates on behalf of Stuart Phinn (UQ) and the JointRemote Sensing Research Program (JRSRP). He noted in particular that the JRSRP haveperformedstate-widevegetationcovermappingforQueenslandandalsopublishedapaperon an operational scheme for deriving standardised surface reflectance from LandsatTM/ETM+andSPOTHRGforEasternAustralia.Theyarealsogeneratingtheirownsurfacereflectance fromSentinel-2and the results correlatewellwithLandsat8.Their cloudandwatermaskingalgorithmsarenowalsorunningoperationally.

Based on this feedback, Brian suggested that CEOS SAR ARDwill likely use the followingprocessingsteps,anddefine‘Target’and‘Threshold’levelsofcomplianceasperthefollowingtable.ThefinalCARD4Lproductisbackscatterintensity(unitless).

Pierre directed Brian to the ESA Thematic Exploitation Platform (TEP) teams for furtherguidanceonanythematicquestions.

CARD4LWorkingSession

AdamLewis(GA)presentedanoverviewoftheCARD4LProductFamilySpecifications(PFS)and Assessment Framework. He reported that the PFS are now formatted as standalonedocuments,andhereviewedanexampleforsurfacereflectance–makingchangesbasedonfeedback receivedwhilewalking through thedraft. Itwasagreed that thePFSshouldnotcover data discoverability/access, as they are about products rather than theirdelivery/discoverymethod.

A discussion followed on the target and threshold definitions. Brian Killough (NASA/SEO)questioned the definition for normalisation (data is normalised for solar-zenith angle(altitude))–suggestingthatitshouldbeathresholdrequirement.InresponsetoDavidJarrett(NASA), Adam clarified thatwhile ‘threshold’ is acceptable, ‘target’ requirements are thedesired level that will most likely increase data uptake and use. Gene Fosnight (USGS)suggestedthatthe‘target’requirementsneedtobeachievableandactasanencouragementforproductimprovement.JennLacey(USGS)suggestedthatthetargetsshouldhavesomereferencetointeroperabilityenhancement.MarkDowell(EC/JRC)notedthatintheClimateDataRecordcontext,theterm‘target’isusedtorefertoimprovementsexpectedovera5-to10-yeartimehorizon.Brianconfirmedthathalfapixelisagoodthresholdaccuracy,whilelessthanathirdofapixelisasuitable‘target’accuracy,asthisensuresthatAWiFSandAVNIRarecovered by the PFS, for example.

LSI-VCandCommercialDataSupplyinFutureActivities

JonathonRoss(GA,CEO)recalledthedrivingforcebehindCARD4L:thereisagroupofnon-expertusersthatarecurrentlyunder-served,andwecanworktoprovidedatathatbesthelpsthem.Henotedthatcommercialdataisalsoavailableandrelevant,andmanyCEOSAgencieshave close relationships with the private sector. Jonathon asked what role CEOS/LSI-VCcould/shouldplayinsupportingeasyaccesstoanduseofcommercialdata.Hesuggestedthepossibilityof ‘pixel renting’andobservationgapfilling,andheaskedwhetherthere is thepossibility of commercial CARD4L offerings. Some questionswere raised in regard to thepossibilityofcommercialCARD4L:

• Mustthedatasetbefullyfree-and-open?Couldtheproductsbedown-sampledversionsofcommercialdatasetsorperhapsglobalmosaics?

• Doestheprocessingchainhavetobeopen?• HowdoesCEOSdealwithacommercialproviderseekingCARD4Lapproval?• HowshouldthepeerreviewofCARD4Lcompliancebecoordinated?

KurtThome(NASA,WGCVChair)notedthatcommercialprovidersarenotrepresentedatthetop-level of WGCV, however some of the WGCV subgroups include private sectorrepresentatives. Their involvement is purely instructive, focusing on protocols,methodologies, and best practices. Jenn Lacey (USGS) supported theWGCV approach tocommercial engagement, suggesting that providing a CARD4L ‘stamp’ for private sectorproductsmightnotbeappropriate.MarkDowell(EC/JRC)agreed,notingthatsuchasituationcouldbecomplicated,especiallyifCARD4Lweretoenduphavingsomemonetaryvalue.Itwasagreed thatwhilewecannot stopcompanies self-assessing theirproductsasCARD4Lcompliant,CEOSshouldnotbedoingassessmentsfortheprivatesector.

Mark Dowell (EC/JRC) asked whether CEOS Agencies have had success working with theprivate sector to release down-sampled/higher-level products derived from commercialdatasets.TheJAXAALOS/JERSglobalmosaicswerenoted,andPaulBriand(CSA)agreedtosharesomeexamplesfromCanada.IvanPetiteville(ESA)notedtheexampleofWGDisasters,which uses commercial data for pilot activities. In this case, non-redistributable data isprovided by companies to specific users for particular applications, and they generallyconsideritanopportunitytopromotetheirpaidproducts.

Adiscussionfollowedonthebestwaytodefinethesetargetproducts.SuggestionsincludedtheparametersfromtheCEOSMIMDatabase,theCEOSCarbonStrategy,andtheGCOSIP.MarksuggestedreferencingtheGCOSIP,astheparametershavequantitativevaluestiedtothem.

BrianKillough(NASA/SEO)requestedclarificationontheendgoal–whatwillbedoneoncethe table is filled out? If this is a gap analysis,willwe be identifyingmeasurement gaps,coveragegaps,etc.?Whatdowedowith thegap information? Itwassuggested that theinformation could be compiled and presented to CEOS as a series of findings andrecommendations, in an attempt to influence futuremission/instrumentdevelopment, aswiththeECVInventorygapanalysis.

Itwasagreedthatfillingoutthetablewillbealargetask,andwillrequireexpertknowledge.Marksuggestedthatoncecomplete,thetemplatebeprovidedtotheGEOCarbonandGHGInitiative team to fill out, as this is in line with GEO’s responsibilities.

• Itshouldbenotedthattheneedfordomainengagementmay‘scaleup’insomedomainsforawhilebeforescalingback,butitisnotalinkthatwewanttolose.

• DesiredoutcomesfromanLSI-VCperspective:

o Gather information about applications for use in communications/promotionactivities?

o Gather feedbackonwhereARD isheaded, forexample through thepilots,butalso‘theoretical’ perspectives. Perhaps gain some insights in terms of specificationrefinementpriortoPlenary?
