title: GBD-MAPS-Global: Gridded Fractional Source Contribution Results

description: <strong>Overview</strong><br> 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:<br> McDuffie, E. E., Martin, R. V., Spadaro, J. V., Burnett, R., Smith, S. J., O'Rourke, P., Hammer, M., van Donkelaar, A., Bindle, L., Shah, V., Jaegle, L., Luo, G., Yu, F., Adeniran, J., Lin, J., Brauer, M. Source Sector and Fuel Contributions to Ambient PM<sub>2.5</sub> Attributable Mortality Across Multiple Spatial Scales, <em>Nature Communications</em> <strong>Notes:</strong><br> All results provide the modeled fractional contribution of each designated source category to total surface PM<sub>2.5</sub> 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 <em>absolute</em> contributions of each source to PM<sub>2.5</sub> mass (used in the GBD-MAPS analysis):<br> 1) Multiply the 0.01°x0.01° fractional source contributions by downscaled 0.01°x0.01° resolution PM<sub>2.5</sub> mass estimates, available in the DownscaledPM.zip folder as part of the GBD-MAPS-Global: Analysis Input Dataset (DOI: 10.5281/zenodo.4642700) <strong>Data File Descriptions:</strong><br> <strong>LatLon</strong> -
