Description

The Visible Infrared Imaging Radiometer Suite (VIIRS) daily surface reflectance (VNP09GA) product provides an estimate of land surface reflectance from the Suomi National Polar-Orbiting Partnership (S-NPP) VIIRS sensor. Data are provided for three imagery bands (I1, I2, I3) at nominal 500 meter resolution (~463 meter) and nine moderate-resolution bands (M1, M2, M3, M4, M5, M7, M8, M10, M11) at nominal 1 kilometer (~926 meter) resolution. The 500 meter and 1 kilometer datasets are derived through resampling the native 375 meter and 750 meter VIIRS resolutions, respectively, in the L2 input product. These bands are corrected for atmospheric conditions to provide an estimate of the surface spectral reflectance as it would be measured at ground level.

The data is temporally aggregated over each of the 16 possible passes per day. When multiple observations are present for each day, only the first of the highest-quality observations is included.

For additional information, visit the VIIRS Land Product Quality Assessment website and see the User Guide.
