Fire Information for Resource Management System (FIRMS)

NASA's Fire Information for Resource Management System (FIRMS) distributes Near Real-Time (NRT) active fire data within 3 hours of satellite observation from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and NASA's Visible Infrared Imaging Radiometer Suite (VIIRS).

MODIS Active Fire Products

MODIS Active Fire Products

Collection 6 has been available since September 2015. Find out more about the most recent MODIS version. MODIS NRT active fire products (MCD14DL) are processed using the standard MOD14/MYD14 Fire and Thermal Anomalies product. Each MODIS active fire location represents the center of a 1km pixel that is flagged by the algorithm as containing one or more fires within the pixel.

VIIRS Active Fire Products

VIIRS Active Fire Products

Note: False fires reported due to super heated smoke plume in nighttime detections (3 August 2018)

New: VIIRS NRT 375 m active fire products (VNP14IMGTDL_NRT) complements MODIS fire detections but the improved spatial resolution of the 375 m data provides a greater response of fires over relatively small areas. The 375 m data also has improved nighttime performance. Read more on VIIRS Active Fire products.

Please note, in an effort to standardize VIIRS file names, the short name for VIIRS NRT 375 m product was changed from VNP14IMGT to VNP14IMGTDL_NRT (18 April 2016).

3 August 2018: During the recent California fires some spurious VIIRS night time fire detections have been picked up due to super heated smoke plumes combined with a high view angle. Read an explanation for these events. Such incidents are rare but we suggest you exercise caution when displaying the VIIRS night time fires.
