VIIRS BRDF/Albedo/NBAR - Inter-comparison with MODIS
The VNP43 product will deliver climate-quality consistent daily Suomi-NPP VIIRS Albedo, Bidirectional Reflectance Distribution Functions (BRDF), and Nadir BRDF-Adjusted Reflectance (NBAR) quantities. This product will include new narrow-to-broadband coefficients (N2B) and production of gap-filled climate modeling grid (CMG) products. This project supports of the Direct Broadcast and near real time (NRT) communities and builds on the long standing MODIS heritage by producing and delivering an algorithm for Suomi NPP VIIRS that includes extensive accompanying quality and uncertainty information for the user.
The products are provided in standard Hierarchical Data Format–Earth Observing System (HDF-EOS5) format. Currently, this collection is available January 19, 2012 and forward. Products from the VIIRS sensor aboard JPSS-1 (J1) will be also be available starting in mid-2023.
