Fire Inventory from NCAR version 2 Fire Emission

The Fire INventory from NCAR (FINN) provides daily global fire emissions at high spatial resolution. The FINN model uses satellite detection of active fires (thermal anomalies) and the land cover type to determine the emission estimates. The emission estimates are based on two uses of satellite observations: (1) MODIS fire detection, (2) Both MODIS and VIIRS (Visible Infrared Imaging Radiometer Suite) active fire detection.

Global daily emission estimates of key gases and aerosols as well as the speciation of the total VOC emissions for three common chemical mechanisms (MOZART-T1, SAPRC99 and GEOS-Chem) are included. Results are available in yearly files at 0.1 by 0.1 degree resolution, or in yearly text files of fire spots at 1 km resolution.

The files for 2024 and 2025 are produced with new software, so are labeled FINN v2.9.1, but the results are based on the identical algorithms of FINN v2.5, and the output is in the same format. Only text files for each fire, tarred and compressed are provided (not 0.1 by 0.1). There are files for each year for both MODIS and MODIS + VIIRS versions.

The variables listed below are only partial of the variables in this dataset. For the complete list of variables, see detailed metadata [https://rda.ucar.edu/datasets/ds312.9/detailed_metadata/]
