VIIRS/JPSS2 BRDF/Albedo BSA at Solar Noon Band VIS Daily L3 Global 30ArcSec CMG V002

The NOAA-21 Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Black-Sky Albedo for Band VIS (VJ243D63) is produced daily using 16 days of data at 30 arc second (1,000 meter) resolution. Data are temporally weighted to the ninth day, which is reflected in the file name. The VJ243D product suite is provided in a Climate Modeling Grid (CMG), which covers the entire globe for use in climate simulation models. Due to the large file size, each VJ243D product contains just one data layer. VJ243D54 through VJ243D79 are the albedo products of the VNP43D BRDF/Albedo product suite. Black-sky albedo (BSA) and white-sky albedo (WSA) values are provided for the nine VIIRS moderate resolution bands (M1 through M5, M7, M8, M10, and M11) along with the visible, near-infrared (NIR), and shortwave bands included in the [VJ243MA3](https://doi.org/10.5067/VIIRS/VJ243MA3.002) product. In addition to the bands included in VJ243MA3, this product suite includes albedo values for the VIIRS Day/Night Band (DNB). The black-sky albedo (directional hemispherical reflectance) is defined as albedo in the absence of a diffuse component and is a function of solar zenith angle. White-sky albedo (bihemispherical reflectance) is defined as albedo in the absence of a direct component when the diffuse component is isotropic. Details regarding methodology are available on the VJ243MA3 product page and in the Algorithm Theoretical Basis Document (ATBD). VJ243D63 is the BSA for the VIIRS visible broadband (0.64 μm).
