STAR JPSS
Visible Infrared Imaging Radiometer Suite (VIIRS)

Team Lead: Changyong Cao, Slawomir Blonski


Visible Infrared Imaging Radiometer Suite (VIIRS) from JPSS satellite

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.
