SUOMI NPP VIIRS: Raytheon's Visible Infrared Imager Radiometer Suite

VIIRS was launched into orbit aboard the Suomi NPP satellite in October 2011.

Raytheon's Visible Infrared Imager Radiometer Suite (VIIRS) was the focus of a high-profile panel discussion at this week's annual meeting of the American Meteorological Society.

The consensus among the panel's meteorologists: VIIRS is opening up exciting new possibilities for weather and climate monitoring.

Commenting on VIIRS' unique day-night band, which enables the capture of highly detailed imagery in extremely low-light conditions, Steve Miller, an atmospheric scientist at Colorado State University's Cooperative Institute for Research in the Atmosphere, said: "VIIRS allows us to use the moon as a surrogate for the sun, providing visibility into nighttime weather and atmospheric conditions with incredible detail never before possible. This makes it a very powerful asset for operational forecasting."

VIIRS was launched into orbit aboard the Suomi NPP satellite in October 2011. Suomi NPP, a NASA-NOAA joint mission, is the precursor to a series of spacecraft that will make up the NOAA Joint Polar Satellite System, which is intended to provide critical weather and climate data for the next two decades.

Strabala of the University of Wisconsin enumerated the technological improvements encompassed in VIIRS over legacy systems, including increased scan distance and greater consistency in resolution across each image scan.

As the scientific community continues to learn how to optimize its use of the VIIRS data, Strabala indicated one drawback to the system: "We only have one such instrument on orbit."

Jedlovec, SPoRT project lead at NASA Marshall Space Flight Center in Huntsville, Ala., cited the critical role the VIIRS day-night band played in the aftermath of Superstorm Sandy.

"The VIIRS night-time imagery was provided to disaster relief agencies and allowed emergency teams to expedite their response to hurricane-ravaged areas," he said.

"This unprecedented night-time perspective was a huge help to relief organizations trying to measure the scope of impact."
