"Fires are an important source of atmospheric trace gases and aerosols and represent the most important disturbance agent at the global scale. In addition, deforestation, tropical peatland fires, and areas experiencing increasing fire frequency contribute to the accumulation of atmospheric CO2."

"The Global Fire Emissions Database (GFED) project quantifies global fire extent and emissions. GFED combines satellite observations of fire activity with information on vegetation productivity to estimate gridded monthly burned area and fire emissions, as well as scaling factors that can be used to derive emissions at higher temporal resolution. The resulting datasets are available for download from this website and are intended for use in large-scale atmospheric and biogeochemical studies. The data are updated daily and can also be used to assess the current fire situation across larger regions and compare current fire activity with previous years."

"Fire emissions in GFED are calculated as the product of burned area, fuel consumption, and emission factors. Fuel consumption is determined by the total fuel load or biomass and the fraction of that biomass that is actually consumed by fire, commonly referred to as combustion completeness. Emission factors are used to convert the amount of combusted biomass into emissions of CO2 and other greenhouse gases, aerosols, and a range of atmospheric constituents."

"Burned area for all vegetation types except croplands is based on Chen et al. (2023). This burned area dataset builds on the MODIS MCD64A1 Collection 6 burned area product developed by Giglio et al. (2018), while accounting for errors of omission and commission. Burned area for croplands is derived from the GloCAB dataset of Hall et al. (2023)."
