Data for "Large role of anthropogenic climate change in driving smoke concentrations across the western United States from 1992 to 2020"

The datasets contain (1) aerosol-only GEOS-Chem (version 14.1.1) nested-grid simulations in North America for control (CTL), natural (NAT), and background (BKG) experiments; (2) original GFED4.1s fire emissions; (3) estimated fire emissions under natural climate scenario based on GFED4.1s framework; (4) predicted burned area under observed and natural climate scenarios from the Gaussian Process Models and observed burned area from FPA-FOD. File Description (1) Aerosol-only GEOS-Chem (version 14.1.1) nested-grid simulations in North America for control (CTL), natural (NAT), and background (BKG) experiments Filename: GC_CTL_YYYY.tar.gz, GC_NAT_YYYY.tar.gz, and GC_BKG_YYYY.tar.gz Description: The datasets contain monthly mean concentrations of aerosols, including PM2.5, total organic aerosols, and black carbon from 1997 to 2020. Simulations were performed with GEOS-Chem v14.1.1 in nested-grid of North America at 0.5x0.625 degree spatial resolution. (2) Original GFED4.1s fire emissions Filename: GFED4s_monthly.zip Description: This dataset contains original monthly mean fire emissions from GFED4.1s at 0.25 degree spatial resolution for the period 1997 to 2020. (3) Estimated fire emissions under natural climate scenario based on GFED4.1s framework Filename: GFED4s_monthly_noACC.zip Description: This dataset contains estimated monthly mean fire emissions under natural climate scenario without anthropogenic climate change at 0.25 degree spatial resolution for the period 1997 to 2020. (4) Predicted burned area data under observed and natural climate scenarios from the Gaussian Process Models and observed burned area from FPA-FOD Filename: BA_GPRpre_OBS_1992_2020 Description: This file contains annual burned area from total fires, lightning-ignited fires, and human-ignited fires in five ecoregions predicted by GPR models under observed and natural climate scenarios and observations from FPA-FOD for the period 1992 to 2020.
