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

MODIS Collection 6 has been available since September 2015. Find out more about Collection 6. 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

VIIRS NRT 375 m active fire products (VNP14IMGTDL_NRT from S-NPP and VJ114IMG_NRT from NOAA-20) 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. 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 from S-NPP, the short name for VIIRS NRT 375 m product was changed from VNP14IMGT to VNP14IMGTDL_NRT (18 April 2016).

15 January 2020: VIIRS 375m active fire data from the NOAA-20 satellite has been added to FIRMS. It is available in the FIRMS map and the active fire data downloads. It is not part of the FIRMS fire email alerts but will be added in the near future.

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.
