About


The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor was launched aboard the Suomi National Polar-orbiting Partnership (NPP) satellite on October 28th, 2011 and on January 18th, 2012 cooler doors for the thermal sensor were opened. Within hours data were being retrieved and fire detections produced. The 5 minute swath quicklooks presented here highlight recent fire detections superimposed on RGB images (bands 5-4-3). The VIIRS active fire product was released to the public on October 22nd, 2012 as beta quality back to April 2nd, 2012. On October 23rd, 2013 VIIRS AF data were declared provisional back to October 16th, 2012. Please refer to the FAQ page to read the definitions of beta and provisional data.
