Below you will find information on how to retrieve the three main datasets; burned area, monthly emissions, daily / 3-hourly fields to scale the monthly emissions to higher temporal resolutions, and additional information. Each data file contains 720 columns and 360 rows (and has a 0.5 degree latitude by 0.5 degree longitude spatial resolution). The upper left corner of each file is centered at 179.75W, 89.75N and the lower right corner at 179.75E, 89.75S. Burned area and emission files are zipped ascii files, burned area estimates are also available as .hdf files, and the daily / 3-hourly fields are in NetCDF. The emission fields are also available as NetCDF files from the ECCAD-GEIA website, thanks to Aude Mieville. In the future we will standardize these formats.
The GFED3 burned area data and burned area uncertainty data can be obtained from the following ftp server:
- ftp fuoco.geog.umd.edu (note that you probably need an ftp program to do this)
- login: fire
- pword: burnt
- cd gfed3/monthly
The fourth version of the Global Fire Emissions Database (GFED4) burned area data set provides global, monthly burned area at 0.25-degree spatial resolution from mid-1995 through the present, and higher temporal resolution daily burned area for a subset of the time series extending back to August 2000. The GFED4 burned area data can be obtained as follows:
- ftp fuoco.geog.umd.edu
- login: fire
- pword: burnt
- cd gfed4
Once logged in you will find several README files plus separate directories containing the monthly and daily GFED4 burned area files.
Emissions fields for several trace gases can be downloaded here. Emissions fields are available for carbon (C), dry matter (DM), CO2, CO, CH4, H2, N2O, NOx, non-methane hydrocarbons (NMHC), organic carbon (OC), black carbon (BC), particulate matter 2.5 micron (PM2p5), total particulate matter (TPM), and SO2. In addition, the C4 fraction of carbon emissions is given (C4).
Units are in g species / m2 / month (for example, g CO / m2 / month for CO). Emissions of NOx are reported as NO. The emission factors we used to convert carbon emissions to dry matter emissions, and then to trace gas en aerosol emissions were derived mostly from Andreae and Merlet (2001, with annual updates by Andi [M.O.] Andreae), see here for a list.
The breakdown in emissions can be found here. These values range between 0 and 1; to estimate total emissions from a specific source category these fields have to be multiplied with the total emissions.
The current GFED version is version 3, version 2 data will not be updated but emissions fields for the 1997 - 2008 period can be found here.
Daily / 3-hourly emissions
These scalar fields can be used in combination with monthly emissions files to estimate emissions on a higher temporal resolution.

- Biosphere fluxes: The CASA-GFED biosphere fluxes include NPP, Rh, and fires (BB). Units are in g C / m2 / month. While our model setup is one of a neutral biosphere (at the end of the spin-up period NPP equals Rh and fires), over the 1997 onwards period there is a net source due to deforestation and peat fires. The monthly datafiles are here.
