    • VIIRS/NPP BRDF/Albedo Valid Observation Band M11 Daily L3 Global 30ArcSec CMG V002

    Metadata Updated: February 5, 2026

    The NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Valid Observation Band M11 product (VNP43D50) 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 VNP43D 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 VNP43D product contains just one data layer for each of the parameters included in the VNP43MA2 product. VNP43D40 through VNP43D53 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 VNP43MA2 product page and in the Algorithm Theoretical Basis Document (ATBD).VNP43D50 contains the valid observation quality layer representing each of the 16 days of the retrieval period for VIIRS band M11.Known Issues For complete information about known issues please refer to the MODIS/VIIRS Land Quality Assessment website.Improvements/Changes from Previous Version Improved calibration algorithm and better coefficients for entire Suomi NPP mission. Improved geolocation accuracy and updates to fix outliers around maneuver periods and other events. Corrections to the aerosol quantity flag (low, average, high) mainly over brighter surfaces in the mid to high latitudes such as desert and tropical vegetation areas. This has an impact on the retrieval of other downstream data products such as VNP13 Vegetation Indices and VNP43 BRDF/Albedo. Improved cloud mask input product for corrections along coastlines and artifacts from use of coarse resolution climatology data. Replaced the land/water mask input product with MODIS heritage seven class land/water mask.
