Overview
This dataset contains the modeled gridded fractional source contribution results for the 2021 Global Burden of Disease - Major Air Pollution Sources (GBD-MAPS) - Global study. Fractional results aggregated to the regional, national, and sub-national scales are available as Supplementary Datasets in McDuffie et al., Nature Communications, 2021. 

This GBD-MAPS-Global methodology and results are described in the following article:
McDuffie, E. E., Martin, R. V., Spadaro, J. V., Burnett, R., Smith, S.

Source Sector and Fuel Contributions to Ambient PM2.5 Attributable Mortality Across Multiple Spatial Scales, Nature Communications

Notes:
All results provide the modeled fractional contribution of each designated source category to total surface PM2.5 mass and attributable disease burden. Fractional source contribution results are derived from emission sensitivity simulations using the GEOS-Chem 3D global chemical transport model (DOI: 10.5281/zenodo.4718622) and emissions from the Community Emissions Data System (GBD-MAPS update) (DOI: 10.5281/zenodo.3754964), unless otherwise noted. Results are provided at the 0.01°x0.01° (~1 km x 1 km) spatial resolution and are based on original simulations conducted at 2°x2.5° (global) and 0.5°x0.625° (Europe, North America, and Asia regions) degree resolutions. All units are in fractional percentages (e.g., 0.0245 is 2.45%). 

To calculate gridded absolute contributions of each source to PM2.5 mass (used in the GBD-MAPS analysis):
1) Multiply the 0.01°x0.01° fractional source contributions by downscaled 0.01°x0.01° resolution PM2.5 mass estimates, available in the DownscaledPM.zip folder as part of the GBD-MAPS-Global: Analysis Input Dataset (DOI: 10.5281/zenodo.4642700)
