VIIRS/JPSS1 BRDF/Albedo Valid Observation Band M5 Daily L3 Global 30ArcSec CMG V002
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/viirs/vj143d46.002
The NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Valid Observation Band M5 product (VJ143D46) is produced daily using 16 days of data at 30 arc second (1,000 meter) resolution.
Description
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 for each of the parameters included in the VJ143MA2 product. VJ143D40 through VJ143D53 are the 30 arc second BRDF/Albedo Quality values, the Local Solar Noon values, the Valid Observations of the moderate resolution bands (M1 through M5, M7, M8, M10, and M11) plus the Day/Night Band (DNB), the Snow Status, and the Uncertainty.

Details regarding methodology are available on the VJ143MA2 product page and in the Algorithm Theoretical Basis Document (ATBD). VJ143D46 contains the valid observation quality layer representing each of the 16 days of the retrieval period for VIIRS band M5.
