The Land Processes Distributed Active Archive Center (LP DAAC) announced the availability of the Visible Infrared Imaging Radiometer Suite (VIIRS) Version 2 Bidirectional Reflectance Distribution Function (BRDF)/ Albedo model parameters, snow-free model parameters, albedo, and Nadir BRDF-Adjusted Reflectance (NBAR) in a global Climate Modeling Grid (CMG) at 0.05 degree (5,600 meters at the equator). VIIRS Version 2 includes data products from both the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite and the NOAA-20 satellite which was previously called Joint Polar Satellite System-1 (JPSS-1).
Details on product improvements for Version 2 are provided on the Digital Object Identifier (DOI) landing pages. Suomi NPP VIIRS Version 1 BRDF/Albedo model parameter data products will remain available and will continue with forward processing through January 31, 2025.
A total of 8 products are included in this release. A list of all products can be found on the Data Catalog.
