This dataset provides global estimates of monthly burned area, monthly emissions and fractional contributions of different fire types, daily or 3-hourly fields to scale the monthly emissions to higher temporal resolutions, and data for monthly biosphere fluxes. The data are at 0.25-degree latitude by 0.25-degree longitude spatial resolution and are available from June 1995 through 2016, depending on the dataset. Emissions data are available for carbon (C), dry matter (DM), carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), hydrogen (H2), nitrous oxide (N2O), nitrogen oxides (NOx), non-methane hydrocarbons (NMHC), organic carbon (OC), black carbon (BC), particulate matter less than 2.5 microns (PM2.5), total particulate matter (TPM), and sulfur dioxide (SO2) among others. These data are yearly totals by region, globally, and by fire source for each region. This Version 4, R1 dataset includes data described as GFED4 and GFED4.1s from the data provider. GFED4 data are without small fire inputs and are in HDF format. The GFED4.1s data include small fires and are provided in HDF5 format. The mapped burned area is without small fires, and this is the GFED4 burned area described in Giglio et al. (2013). The emissions fields are based on this dataset but boosted with small fires, GFED4.1s. The emissions fields also contain a layer with the fraction of emissions resulting from this boost. Additional information may be obtained from the Global Fire Data website: http://www.globalfiredata.org/index.html. The dataset is divided into the following main datasets. Data products include:
Global monthly burned area (ha) at 0.25-degree x 0.25-degree for 1997 to 2016 in HDF (.hdf) format (GFED4). Global daily burned area for a subset of the time series from Aug 2000 to 2015 in HDF (.hdf) format (GFED4). 2. Emissions (monthly, daily, 3-hourly) and burned area (GFED4s - with small fires) Annual files with monthly GFED4s burned area (including small fires), emissions, and scalars to distribute the monthly emissions over the days as well as the diurnal cycle as HDF5 (.hdf5) format (GFED4s) for the time period 1997 to 2015. These files contain fire carbon emissions (g C m-2 month-1) and dry matter emissions (kg DM m-2 month-1). In addition, fractional contributions of different fire types (grassland and savanna, woodland, deforestation and degradation, forest, agricultural waste burning, and peat fires) are provided within each file. The CASA-GFED biosphere flux sources include Net Primary Production (NPP), heterotrophic respiration (Rh), and fires (biomass burning). Rh has been updated for all years in this distribution due to a correction in only the Rh values. Available for years 2003 onward are daily / 3-hourly emissions which are scalar fields that can be used in combination with monthly emissions files to estimate emissions on a higher temporal resolution. Regional estimates for various trace gases and aerosol emissions are provided, in text format, that contain annual emissions (1997 - 2016) per region for totals of C and individual species from all sources, yearly lumped sources such as higher alkanes, higher alkenes, and toluenes, and from each individual fire source (forest fires, peat fires, agricultural waste burning, etc). These files are for indicative use only; they are not suitable for official reporting due to large uncertainties and the potential for aspects of information from key regions to be missing in the global approach used. There are 41 text files. Related files include emission factors (EF) data for individual species by biome (fire source) in comma-separated (.csv) format. There are 2 csv files. There are a total of 5,952 files with this dataset. The data are in text, HDF5, and HDF formats as described above. |
