GeoColor is a multispectral product composed of True Color (using a simulated green component) during the daytime, and an Infrared product that uses bands 7 and 13 at night. During the day, the imagery looks approximately as it would appear when viewed with human eyes from space. At night, the blue colors represent liquid water clouds such as fog and stratus, while gray to white indicate higher ice clouds, and the city lights come from a static database that was derived from the VIIRS Day Night Band.
Geocolor was developed at the Cooperative Institute for Research in the Atmosphere (CIRA) and STAR's Regional and Mesoscale Meteorology Branch (RAMMB). For a full description of the algorithm, please see this journal article.
