NASA’s Fire Information for Resource Management System (FIRMS) distributes near real-time (NRT) active fire data within three hours of a satellite observation from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS). FIRMS is part of NASA’s Land, Atmosphere Near real-time Capability for EOS (LANCE).
