VIIRS active fires

The VIIRS (Visible Infrared Imaging Radiometer Suite) on board of the NASA/NOAA Suomi National Polar-orbiting Partnership (SNPP) identifies areas on the ground that are distinctly hotter than their surroundings to detect active fires. The VIIRS active fire products complements the MODIS active fire detection and provides an improved spatial resolution, as compared to MODIS. The spatial resolution of the active fire detection pixel for VIIRS is 375 m. Additionally, VIIRS is able to detect smaller fires and can help delineate perimeters of ongoing large fires.
