The VIIRS sensor aboard the NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) and the NOAA-20 satellites was designed to acquire 22 spectral bands across a wide range of wavelengths in the electromagnetic spectrum. These wavelengths include the visible, near-infrared, shortwave infrared, and thermal infrared and are used to collect data to study various phenomena that occur on the Earth and in our atmosphere.
The VIIRS instruments acquire data in two native spatial resolutions:
- Bands I1-5: 375m
- Bands M1-16: 750m
The higher level VIIRS land products are produced at three nominal spatial resolutions: 500 m; 1,000 m; and 5,600 m (0.05 degrees).
