VIIRS/JPSS1 BRDF/Albedo Parameter 3 VIS Daily L3 Global 30 ArcSec CMG V002

The NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Model Parameter 3 VIS product (VJ143D30) 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 (VIS), 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). VJ143D30 is the BRDF geometric parameter for the VIIRS visible broadband (0.64 μm). The geometric parameter, in conjunction with the isotropic and volumetric parameters, is used to derive the BRDF/Albedo values for the VIIRS visible broadband. Known Issues * For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website]( https://landweb.modaps.eosdis.nasa.gov/knownissue). Improvements/Changes from Previous Versions The NOAA-20 VIIRS algorithms include the same improvements as the S-NPP VIIRS V002 * Improved calibration algorithm and better coefficients for entire NOAA-20 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 VJ113 Vegetation Indices and VJ143 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

VIIRS/JPSS1 BRDF/Albedo Snow-free Model Parameters Daily L3 Global 0.05Deg CMG V002

The NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Snow-free Model Parameters Daily Global 0.05 Degree Climate Modeling Grid (CMG) Version 2 product (VJ143C2) is derived from the 30 arc second CMG VJ143D Version 2 product suite. VJ143C2 is generated daily from all available snow-free acquisitions over a 16-day moving window emphasizing the ninth day of the retrieval period, which is reflected in the Julian date in the filename. VJ143C2 supplies the weighting parameters associated with the RossThick/Li-Sparse-Reciprocal BRDF model, which is used to produce the [VJ143C3](https://doi.org/10.5067/VIIRS/VJ143C3.002) Albedo and [VJ143C4](https://doi.org/10.5067/VIIRS/VJ143C4.002) Nadir BRDF-Adjusted Reflectance (NBAR) products. The highest quality full inversion values are used for the temporal fitting effort and supplemented with lower quality pixels, spatial fitting, and spatial smoothing as needed. The status of each pixel can be found in the ancillary layers. Users are encouraged to assess the quality information before using the BRDF/Albedo data. This 0.05 degree (5,600 meters at the equator) CMG product covers the entire globe for use in climate simulation models. The VJ143C2 product includes 39 layers containing the three parameters (fiso, fvol, and fgeo) for the VIIRS Day/Night band (DNB), moderate resolution bands M1 through M5, M7, M8, M10, and M11, as well as the shortwave band, visible band, and near-infrared (NIR) broadbands. Along with the parameter data for the 13 bands are four ancillary layers for uncertainty, quality, local solar noon, and percent finer resolution inputs.
