Description

The Joint Polar Satellite System-1 (JPSS-1) Visible Infrared Imaging Radiometer Suite (VIIRS) surface reflectance products provide estimates of surface reflectance derived from the following twelve VIIRS reflective bands: I1-I3 (I-bands at 375 m resolution), M1-M5, M7, M8, M10, and M11 (M-bands at 750 m resolution). VJ109 is the short-name for the L2 orbital swath-based atmospherically corrected surface reflectance product at 375 m and 750 m resolutions.
The VJ109 contains approximately 6 minutes' worth of data. Surface reflectance for each moderate-resolution or imagery-resolution pixel is retrieved separately for the Level-2 products. Surface reflectance is obtained by adjusting top-of-atmosphere reflectance to compensate for atmospheric effects. Corrections are made for the effects of molecular gases, including ozone and water vapor, and for the effects of atmospheric aerosols. All surface reflectance products are produced for daytime conditions only. The product is produced under all atmospheric conditions except for night and oceans.
