Summary:

NASA’s Short-term Prediction Research and Transition (SPoRT) Center at Marshall produces false color composites of Suomi-NPP VIIRS instrument day night band (DNB) radiance and infrared cloud and land surface temperatures (M15). DNB imagery is assigned to red and green channels and brightness temperatures to blue shades, allowing a combined display of nighttime lights, fires, reflected moonlight and occasional lightning in shades of yellow (new moon) to white (full moon) along with blue tinting of cloud imagery. This color combination is based upon usage developed by the Naval Research Lab and shared with partners in NOAA’s National Weather Service.

Suggested Use:

In this image, city lights appear in bright shades of yellow to white when not obscured by clouds (shades of blue to white). Visual comparisons of pre- and post-event scenes allow for subjective identification of where lights are missing as a result of disaster impacts on local infrastructure that have caused damages to structures or utilities. The product does not account for the source of the light and should not be used as an operational tool.

Satellite/Sensor:

Suomi National Polar-Orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) use of the day-night band and M15 thermal infrared band. S-NPP is a joint mission between NASA and NOAA. Similar capabilities are available from the NOAA-20 mission.
