For satellite ocean color to be reliable and used in these and other important environmental applications, the data must be trustworthy and high quality. Pre-flight and on-board calibration of satellite ocean color sensors is conducted; however, once in orbit, the data quality can only be fully assessed via independent calibration and validation activities using surface measurements. These measurements therefore need to be at least as high quality as the satellite data, which necessitates SI traceability and a full uncertainty budget. This is the basis for fiducial reference measurements (FRMs) and the FRM4SOC project, which was an European Space Agency (ESA) initiative to establish and maintain SI-traceable ground-based FRM for satellite ocean color, thus providing a fundamental contribution to the European system for monitoring the Earth (Copernicus). This Special Issue of MDPI Remote Sensing is designed to showcase this essential Earth observation work through the publication of the project's main achievements and results accompanied by other select relevant articles.Research and information: generalbicsscAcqua Alta Oceanographic TowerAERONET-OCagreement between sensorsAquaatmospheric correctionautonomous measurementsBOUSSOLEcalibrationcalibration and validationcoastal environmentCommittee for Earth Observation Satellites (CEOS)Copernicusdata mergingdesert trendDINEOFdownwelling irradianceEuropean Space Agency (ESA)fiducial reference measurementfiducial reference measurementsFiducial Reference Measurementsfiducial reference measurements (FRM)field intercomparisonfield intercomparison measurementgap-fillingground-truth datahyper-temporal datasetHyperspectral reflectanceindoor intercomparison measurementLampedusalunar calibrationMarONetmeasurement uncertaintyMediterranean SeaMOBYMODISMSEANOAA-20observation geometryocean colorocean color dataocean color radiometersocean colourocean colour radiometersoptical radiometryradiometric calibrationradiometryremote sensingremote sensing reflectanceresearch infrastructureRVSsatellitesatellite ocean coloursatellite validationSDSMSeabird HyperSASSentinel-3 OLCISI traceability and uncertaintySI-traceabilitySNPPsolar diffusorspectral irradiance comparisonspectral radiance sources comparisonsystem designsystem vicarious calibrationTriOS RAMSESuncertainty budgetvalidationVIIRSwater reflectancewater-leaving radianceResearch and information: generalBanks Andrew Cliveedt1297579Lerebourg ChristopheedtRuddick KevinedtTilstone GavinedtVendt RihoedtBanks Andrew CliveothLerebourg ChristopheothRuddick KevinothTilstone GavinothVendt RihoothBOOK9910557797803321Fiducial Reference Measurements for Satellite Ocean Colour3024570UNINA
