by **LP DAAC - jwilson** » Tue Jan 21, 2025 10:48 pm America/New_York

The LP DAAC is pleased to announce the availability of the Visible Infrared Imaging Radiometer Suite (VIIRS) Version 2 Bidirectional Reflectance Distribution Function (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 spatial resolution for the VIIRS Day/Night Band (DNBA). 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 during this transition.

A total of 8 products are included in this release. A list of all products can be found on the LP DAAC website. Sample citations containing the Digital Object Identifier (DOI) for VNP43DNBA1 and VJ143DNBA1 are provided below.
