Portugal Fire Anomaly Satellite Detection
Active Fire Anomaly Detection & Alert for situation awareness & Resource Management is streamed from NASA’s TERRA (EOS) satellite MODIS (Moderate Resolution Imaging Spectroradiometer) and SUOMI NPP satellite VIIRS (Visible Infrared Imaging Radiometer Suite) sensors 3 hrs after acquisition. The detection and alert is offered free.
Note: Fire & thermal anomaly data may be from fire, hot smoke, crop burning, or other causes and sources.
NASA states that Each MODIS active fire/thermal hotspot location represents the center of a 1km pixel that is flagged by the algorithm as containing one or more fires within the pixel. Combined (Terra and Aqua) MODIS NRT active fire products (MCD14DL) are processed using the standard MOD14/MYD14 Fire and Thermal Anomalies algorithm. Each VIIRS active fire/thermal hotspot location represents the center of a 375m pixel. The VIIRS data complement the MODIS fire detections but the improved spatial resolution of the 375 m data provides a greater response of fires over relatively small areas and has improved nighttime performance.
