Description
The NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo (BRDF/Albedo) Version 2 product provides albedo estimates at 1000 meter (1 km) resolution. The VNP43MA3 product is produced daily using 16 days of VIIRS data and is weighted temporally to the ninth day. It provides both directional hemispherical reflectance (black-sky albedo) at local solar noon and bihemispherical reflectance (white-sky albedo) for the nine VIIRS moderate resolution bands (M1-M5, M7-M8, M10-M11) and three broadbands (vis, nir, and shortwave). The VNP43 data products are designed to promote the continuity of NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) BRDF/Albedo data product suite.
The VNP43 algorithm uses the RossThick/Li-Sparse-Reciprocal (RTLSR) semi-empirical kernel-driven BRDF model to reconstruct surface anisotropic effects, computing integrated black-sky albedo (BSA) at local solar noon and white-sky albedo (WSA) (VNP43MA3). Researchers can use the BRDF model parameters with a simple polynomial, to obtain black-sky albedo at any solar illumination angle. Likewise, both the BSA and WSA Science Dataset (SDS) layers can be used with a simple polynomial, to manually estimate instantaneous actual albedo (blue-sky albedo). Additional details regarding the methodology are available in the Algorithm Theoretical Basis Document (ATBD).
