VIIRS/JPSS1 BRDF/Albedo Parameter 1 Band M4 Daily L3 Global 30 ArcSec CMG V002

Published by LP DAAC;NASA/GSFC/SED/ESD/TISL/LandSIPS;UMASS-B/SFE | National Aeronautics and Space Administration | Catalog Last Checked: June 09, 2026 at 08:37 PM | Dataset Last Updated: June 08, 2026
The NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Model Parameter 1 Band M4 product (VJ143D10) 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 VJ143D 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 VJ143D product contains just one data layer. Each of the three model parameters (isotropic, volumetric, and geometric) for each of the nine VIIRS moderate resolution bands along with the visible, near-infrared (NIR), and shortwave bands included in the [VJ143MA1](https://doi.org/10.5067/VIIRS/VJ143MA1.002) product is stored in a separate file as VJ143D01 through VJ143D36. In addition to the bands included in VJ143MA1, this product suite includes model parameters for the VIIRS Day/Night Band (DNB) as VJ143D37 through VJ143D39. Details regarding methodology are available on the VJ143MA1 product page and in the Algorithm Theoretical Basis Document (ATBD). VJ143D10 is the BRDF isotropic parameter for VIIRS band M4 (0.555 μm). The isotropic parameter, in conjunction with the volumetric and geometric parameters, is used to derive the BRDF/Albedo values for VIIRS band M4.
