THE SUOMI-NPP AND JPSS ALBEDO BRDF AND NBAR PRODUCTS HAVE BEEN DEVELOPED TO PROVIDE LONG-TERM CLIMATE-QUALITY CONTINUITY WITH THE MORE THAN TWO DECADES OF MODIS PRODUCTS PROVIDED BY THE TERRA AND AQUA MISSIONS. LAND SURFACE ALBEDO IS AN ESSENTIAL CLIMATE VARIABLE (ECV) REQUIRED BY CLIMATE WEATHER HYDROLOGIC AND BIOGEOCHEMICAL MODELERS TO QUANTIFY THE REFLECTIVE CHARACTER OF LAND SURFACES AND THUS ESTIMATE THE SURFACE RADIATIVE FORCING. LAND SURFACE ALBEDO VARIES WIDELY IN SPACE AND TIME AND IS DEPENDENT ON THE LAND COVER VEGETATION STRUCTURE SEASONAL PHENOLOGY VEGETATION CONDITION AND HEALTH SNOW COVER AND DISTURBANCE. THE VIIRS PRODUCTS FROM THE SUOMI-NPP AND THE JPSS (CURRENTLY NOAA-20) MISSIONS PROVIDE DAILY GRIDDED GLOBAL ESTIMATES OF THIS SURFACE VARIABILITY AS BOTH STANDARD PRODUCTS AND AS LANCE NRT PRODUCTS. IN COMPARISONS WITH TOWER ALBEDO DATA FROM SPATIALLY REPRESENTATIVE SITES THEY HAVE BEEN SHOWN TO CAPTURE THE RAPID DAILY VARIATIONS IN ALBEDO CAUSED BY EPHEMERAL SNOWFALL AND MELT SEASONAL PHENOLOGICAL CHANGES AND DISTURBANCE. THE INTRINSIC SURFACE REFLECTANCE ANISOTROPY IS DETERMINED BY FITTING BIDIRECTIONAL REFLECTANCE DISTRIBUTION FUNCTION (BRDF) MODELS TO MULTI-ANGLE CLOUD-FREE SATELLITE REFLECTANCE OBSERVATIONS OF EACH GRID LOCATION. THESE BRDF ESTIMATES ARE THEN INTEGRATED HEMISPHERICALLY OVER ALL VIEW AND ILLUMINATION GEOMETRIES TO GENERATE INTRINSIC WHITE SKY ALBEDO (BIHEMISPHERICAL REFLECTANCE) AND OVER ALL VIEW ANGLES AT A PARTICULAR SOLAR ZENITH ANGLE TO GENERATE BLACK SKY ALBEDO (DIRECTIONAL-HEMISPHERICAL REFLECTANCE AT LOCAL SOLAR NOON). THE BRDF QUANTITIES ARE ALSO USED TO CORRECT DIRECTIONAL SURFACE REFLECTANCES TO A COMMON VIEW ANGLE (E.G. THE NADIR BRDF-ADJUSTED SURFACE REFLECTANCES (NBAR) PRODUCT) AND TO ESTIMATE MEASURES OF SURFACE CANOPY CLUMPING AND STRUCTURE. THE STANDARD VIIRS VIEW-ANGLE-CORRECTED NBAR PRODUCT (PROVIDED AT LOCAL SOLAR NOON) ARE ALSO USED TO GENERATE DOWNSTREAM VIIRS PHENOLOGY PRODUCTS AS WELL AS TO MONITOR THE CONDITION OF FORESTS RANGE LANDS AGRICULTURAL FIELDS AND NATURAL ECOSYSTEMS AND TO ASSESS THE IMPACT OF NATURAL AND MAN-MADE DISTURBANCES (HARVEST DEVELOPMENT FIRE DROUGHT FLOODING STORM DAMAGE ETC.). THE MATURE AND WELL DOCUMENTED DAILY GLOBAL VIIRS ALBEDO BRDF AND NBAR PRODUCTS ARE ACCOMPANIED BY EXTENSIVE QUALITY AND UNCERTAINTY INFORMATION AND THESE HIGH-QUALITY PRODUCTS ARE BEING EMBRACED BY GLOBAL AND REGIONAL MODELING AND MONITORING COMMUNITIES TO EXTEND THE LONG TERM RECORD BEGUN WITH THE MODIS INSTRUMENTS INTO THE FUTURE. THUS THIS EFFORT IS FOCUSED ON THE CONTINUED MAINTENANCE OF HERITAGE SUOMI-NPP AND JPSS VIIRS ALBEDO BRDF AND NBAR PRODUCTS TO PROVIDE A CONSISTENT CLIMATE QUALITY RECORD OF THE RADIATIVE CHARACTER OF THE EARTH S LAND SURFACES.
