The LP DAAC is pleased to announce the availability of the Visible Infrared Imaging Radiometer Suite (VIIRS) Version 2 Albedo, Bidirectional Reflectance Distribution Function (BRDF), and Nadir BRDF-Adjusted Reflectance (NBAR) data products at 500 meter and 1 kilometer spatial resolution. 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). This release covers the joint mission period from year 2018 up to the leading edge for the three VIIRS Imagery bands and nine Moderate bands as well as the information for the three broad bands (VNP43IA[1-4], VJ143IA[1-4], VNP43MA[1-4], and VJ143MA[1-4]). Details on product improvements for Version 2 are provided on the Digital Object Identifier (DOI) landing pages. Suomi NPP VIIRS Version 1 Albedo, BRDF, and NBAR data products will remain available and will continue with forward processing during this transition. Climate Modeling Grids (CMGs) and Day/Night Band (DNB) data products will be released at a later time.
Sample citations containing the DOI for VNP43IA1, VJ143IA1, VNP43MA1, and VJ143MA1 are provided below.
