1. Description

Fire emissions from natural forest and grassland fires as calculated by an ensemble of CMIP6 climate models with interactive fires merged with tropical deforestation and peat fires from the SSPs fire emission dataset. All climate model emissions are biased-corrected towards GFAS4HTAP dry matter consumed (2015-2020 mean). Emission factors used are reported in GFAS4HTAP dataset (https://zenodo.org/records/15721463).

 

A separate file is provided for each species. Each file contains three variables, with emissions from grassland fires, forest fires, and peat fires reported separately.

 

Decades provided are:

2015-2020, 2021-2030, 2031-2040, 2041-2050, 2051-2060, 2061-2070, 2071-2080, 2081-2090, 2091-2100
