NASA/NOAA Suomi NPP VIIRS VNP43IA2 Version 1 is a decommissioned satellite data product providing Bidirectional Reflectance Distribution Function (BRDF) and Albedo quality information at a 500-meter resolution. It is produced daily using a 16-day temporal window weighted to the ninth day and contains 11 Science Dataset layers. The product uses the RossThick/Li-Sparse-Reciprocal kernel-driven BRDF model to reconstruct surface anisotropic effects and compute albedo.
This Version 1 product was decommissioned on July 31, 2025. Users are encouraged to use the VNP43IA2 and VJ143IA2 Version 2 data products.
