Abstract

This dataset contains 2001-2020 burned areas and climate variables for three regions with Mediterranean climates: South America from 31-46 degrees South, including Chile and the forested Andean region of Argentina; the western United States from 33-49 degrees North from the coast extending to the eastern extent of forest, and the Iberian Peninsula, including all of Spain and Portugal.

Burned areas are polygon shapefiles for all regions except Chile, for which the burn area is represented in a point shapefile. The data sources for the fire shapefiles are:
Chile: unpublished, originally from Corporación Nacional Forestal (CONAF) and compiled by Miranda
Argentina: unpublished, compiled by Diego Mohr-Bell and others at Centro de Investigación y Extensión Forestal Andino Patagónico (CIEFAP)
North America: NIFC 2023
Iberian Peninsula: EFFIS 2022

All of the fire shapefiles are contained within the zip folder fire_areas, and the individual regions are ch_fire (Chile), ar_fire (Argentina), na_fire (North America), ib_fire (Iberian Peninsula). The attributes of the shapefiles are the year and the fire area in square kilometers. For Chile, the fire start dates were documented. If the fire started in June-December, the year assigned is advanced by 1 from the original year. This is because the summer fire season straddles the calendar year boundary, and the fire year is assigned based on the year with most of the summer season. For Argentina, the end dates of the fire were available, so these end dates were used to assign the fire year.

Annual summaries of fire area and climate variables are provided in the fire_ann_all.csv file. The columns in this file are:
year
wetdryzone: dry if mean annual aridity index <1; wet if mean annual aridity index >1
cont: location, either Iberian Peninsula, North America, or South America
area_km2: total burned area in square km
AIann: annual aridity index calculated as total precipitation over total potential evapotranspiration
AIjas: summer aridity index for July-September in northern hemisphere; January-March, southern hemisphere
vpd: mean annual vapor pressure deficit (kPa)
vpd_jas: mean summer vapor pressure deficit (kPa)
def: mean annual climatic water deficit (mm)
def_jas: summer climatic water deficit (mm)

Climate data were obtained from TerraClimate (Abatzoglou et al. 2018).

Mean annual summaries of fire and climate data by aridity index zone are provided in the file AI_bins_meanannual.csv. AI zones/bins are in increments of 0.2. Columns are:
cont: location, either Iberian Peninsula, North America, or South America
AI_max: maximum AI for the AI zone. For example, if the value is 0.2, the zone is from AI=0 to AI=0.2
zone_area: total area of the climate zone in square kilometers
forest_area: total area forested in 2000 in square kilometers (Potapov et al. 2022)
fire_area: total area burned from 2001-2020 in square kilometers (same sources as fire shapefiles)
frac_forest: fraction of climate zone area that is forested
frac_fire: fraction of the climate zone area that was burned
mean_patch_area: mean size of forest patches identified within each AI zone in square kilometers
fwi: mean fire weather index from the European Center for Medium-range Weather Forecasts (Vitolo et al. 2020)
