VNP09GA: VIIRS Surface Reflectance Daily 500m and 1km (NOAA/VIIRS/001/VNP09GA)

Version V001

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.

Assessment website
