GOES satellites continually view the continental United States, Pacific and Atlantic Oceans, Central and South America, and Southern Canada. To fully cover Alaska, Hawaii, the entire continental United States and the Pacific and Atlantic Oceans (for tropical storms), NOAA operates two GOES satellites simultaneously: GOES East and GOES West. GOES East is located at 75.2° W and provides most of the U.S. weather information. GOES West is located at 137.2°W over the Pacific Ocean. In addition to two operational satellites, NOAA also maintains an on-orbit spare.
In the last few days there have been many fires in Canada, mainly in the provinces of British Columbia and Alberta. These fires (which have already devoured more than 4 million hectares) are filling the environment with smoke, as can be clearly seen in the EASTERN part of the GIF.
GeoColor is a multispectral product composed of True Color (using a simulated green component) during daytime, and an Infrared product that uses bands 7 and 13 at night. During the day, the imagery looks approximately as it would 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 derived from the VIIRS Day Night Band.
GeoColor was developed at the Cooperative Institute for Research in the Atmosphere (CIRA) and the STAR Regional and Mesoscale Meteorology Branch (RAMMB). For a full description of the algorithm, please see this article.
Please credit CIRA/NOAA when using GeoColor imagery.
NOTE: Lighted areas shown in nighttime images are not real-time depictions of city lights. The layer is derived from a compilation of JPSS VIIRS Day Night Band images and is included for orientation purposes.
