VIIRS/JPSS1 Surface Reflectance 8-Day L3 Global 1km SIN Grid V002

Published by LP DAAC;NASA/GSFC/SED/ESD/TISL/LandSIPS | National Aeronautics and Space Administration | Catalog Last Checked: June 09, 2026 at 08:36 PM | Dataset Last Updated: June 08, 2026
The 8-day Visible Infrared Imaging Radiometer Suite (VIIRS) surface reflectance (VJ109A1) Version 2 composite product provides an estimate of land surface reflectance from the NOAA-20 VIIRS sensor for nine moderate resolution bands (M1 - M5, M7, M8, M10, M11) at nominal 1 kilometer resolution (~926 meter). The 1 kilometer dataset is derived through resampling the native 750 meter VIIRS resolution in the Level 2 input product. The data are corrected for atmospheric conditions such as the effects of molecular gases, including ozone and water vapor, and for the effects of atmospheric aerosols. Each pixel represents the best possible Level 2G observation during an 8-day period that is selected on the basis of high observation coverage, low sensor angle, the absence of clouds or cloud shadow, and aerosol loading. Included in the product along with the fifteen reflectance bands are day of year, reflectance band quality, control, reflectance state quality assurance, relative azimuth angle, sensor zenith angle, and solar zenith angle variables.
