Featured Atmospheric Rivers Observation Method: VIIRS
The Visible Infrared Imaging Radiometer Suite (VIIRS) instruments are aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-platforms. The orbits of the platforms make them ideally positioned to observe atmospheric rivers reaching the west coast of North America. The VIIRS instruments include five high-resolution image bands, sixteen moderate-resolution bands, and one unique panchromatic day/night band ultra-sensitive in low-light conditions. The VIIRS instruments build on the heritage of their successful predecessors, the Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS), and the Sea-viewing Wide Field-of-view Sensor (SeaWIFS).

From MODIS to VIIRS: Continuing the Legacy

The Visible Infrared Imaging Radiometer Suite (VIIRS) will help ensure continuity of Earth observations after the upcoming retirement of the Moderate Resolution Imaging Spectroradiometer (MODIS).

VIIRS-Atmosphere Near Real-Time Data

Near real-time atmosphere data from the Visible Infrared Imaging Radiometer Suite (VIIRS) are available through NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE).
