Description:
The Visible Infrared Imaging Radiometer Suite (VIIRS) has multi-band imaging capabilities to support the acquisition of high-resolution atmospheric imagery and generation of a variety of applied products including visible and infrared imaging of hurricanes and detection of fires, smoke, and atmospheric aerosols.
VIIRS provides operational and research users with:
- Spectral coverage from 412 nm to 12 μm in 22 bands
- Imagery at ~375 m nadir resolution in 5 bands
- Moderate resolution (~750 m at nadir) radiometric quality data
Routine data products
- Cloud cover, cloud layers
- Cloud and aerosol physical properties
- Land & ocean biosphere properties, snow & ice
- Sea Surface Temperature, Land & Ice Temperatures
- Fire detection
- Imagery
Note:
Sensor-order RSRs follow a detector numbering scheme that follows pre- launch protocol. For sensor-order RSRs, Detector 1 leads in the track direction and Detector 16 (32) trails in the track direction. For product- order RSRs, however, Detector 16 (32) leads in the track direction and Detector 1 trails in the track direction.
