Release of VIIRS Bidirectional Reflectance Distribution Function (BRDF)/Albedo Products

By: LP DAAC

The Land Processes Distributed Active Archive Center (LP DAAC) is pleased to announce the availability of 97 new NASA-produced Suomi National Polar-orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF)/Albedo products.

The VNP43DNBA[1-4] data products are a continuation of the VNP43MA product suite providing BRDF/Albedo model parameters (isotropic, volumetric, and geometric), quality, white-sky albedos (WSA), black-sky albedos (BSA), and Nadir BRDF-Adjusted Reflectance (NBAR) at 1 kilometer resolution for the VIIRS Day/Night Band.

The VNP43C[1-3] data products provide BRDF/Albedo model parameters, quality, WSA, and BSA in a global Climate Modeling Grid (CMG) at 0.05 degree (5,600 meters at the equator) resolution for the VIIRS DNB, moderate resolution bands M1 through M5, M7, M8, M10, and M11, as well as the shortwave band, visible band, and near-infrared (NIR) broadbands. The VNP43C4 data product offers NBAR for VIIRS DNB and moderate resolution bands M1 through M5, M7, M8, M10, and M11.

The VNP43D[01-89] products include BRDF/Albedo data products representing each individual layer in the VNP43C product suite as a global Climate Modeling Grid (CMG) at 30 arc second (1,000 meter) resolution. Due to the large file size, each VNP43D product contains just one data layer.

Sample citations containing the Digital Object Identifier (DOI) for VNP43DNBA1, VNP43C1, and VNP43D01 are provided below.
