CEDS_GBD-MAPS: Global Anthropogenic Emission Inventory of NOx, SO2, CO, NH3, NMVOCs, BC, and OC from 1970-2017

CEDS_GBD-MAPS: Global Anthropogenic Emission Inventory of NO_x, SO₂, CO, NH₃, NMVOCs, BC, and OC from 1970-2017

version tag: 2020_v1.0 (April 2020)

Annual anthropogenic emissions of 7 key atmospheric pollutants from 1970 - 2017, produced using the Community Emissions Data System, updated for the Global Burden of Disease - Major Air Pollution Sources project (CEDS_GBD-MAPS).

Emissions are provided for NO_x, SO₂, CO, NH₃, NMVOCs, Black Carbon (BC), and Organic Carbon (OC) from 11 anthropogenic sectors and four fuel categories as both annual country totals and global gridded emission fluxes (0.5 x 0.5 degree resolution).
Note: The CEDS_GBD-MAPS inventory does not include emissions from open fires or aircraft.
Sectors: 
1. Agriculture (non-combustion sources only, excludes open fires)
2. Energy (transformation and extraction)
3. Industry (combustion and non-combustion processes)
4. On-Road Transportation
5. Off-Road/Non-Road Transportation (rail, domestic navigation, other)
6. Residential Combustion
7. Commercial Combustion
8. Other Combustion
9. Solvents
10. Waste (disposal and handling)
11. International Shipping
Fuel Categories:
1. Total Coal Combustion (hard coal + brown coal + coal coke)
2. Solid Biofuel Combustion
3. Liquid Fuel (light oil + heavy oil + diesel oil) plus Natural Gas Combustion
4. CEDS Process Source Categories (see McDuffie, et al., (ESSD) 2020) for further details.
Note: Total anthropogenic emissions = the sum of fuel categories 1-4

Zip File Details:
The CEDS_GBD-MAPS inventory is available in three different formats:

1. CEDS_GBD-MAPS_annual_country_total_emissions_by_sector_fuel_1970-2017.zip

• Zip file contains 7 .csv files that each contain a complete times series (1970-2017) of total annual anthropogenic emissions of each compound from each country, as a function of 11 anthropogenic sectors and 4 fuel categories.
• Emissions are in units of kt yr^-1 and include NO_x (as NO₂), CO, SO₂, NH₃, total NMVOCs, BC, and OC

2. CEDS_GBD-MAPS_gridded_emissions_by_sector_fuel_[year].zip

• Each .zip file contains 145 netCDF files of annual anthropogenic global gridded emission fluxes, reported as a function of 11 anthropogenic sectors and 5 fuel categories (1 file per compound per fuel category, plus 1 file for the sum of all fuel categories)
• Emission fluxes are in units of kg m^-2 s^-1 and include NO_x (as NO), CO, SO₂, NH₃, 25 speciated VOCs, BC, and OC
• Emission fluxes are provided as monthly averages and have been formatted for use in the GEOS-Chem model (http://acmg.seas.harvard.edu/geos/).
• Example: ALD2-em-liquid-fuel-plus-natural-gas_CEDS_1970.nc inside the CEDS_GBD-MAPS_gridded_emissions_by_sector_fuel_1970.zip file provides monthly emission fluxes in 1970 for the subVOC ALD2 that result from the combustion of liquid fuel and natural gas in each of the 11 source sectors.

3. CEDS_GBD-MAPS_[compound]_gridded_total_anthro_emissions_by_sector_input4CMIP_1970-2017.zip

• compound = [BC_OC], [CO_NOx_SO2_NH3], [speciated_NMVOCs_01-04], [speciated_NMVOCs_05-08], [speciated_NMVOCs_09-14], [speciated_NMVOCs_15-18], [speciated_NMVOCs_19-22], or [speciated_NMVOCs_23-25]
• Each .zip file contains between 2 - 4 netCDF files (1 per compound) of anthropogenic global gridded emission fluxes from 1970-2017, as a function of 11 anthropogenic sectors only (no disaggregation of fuel categories)
• netCDF files follow the CEDS CMIP6 gridded emissions format. More information available at: 
  http://www.globalchange.umd.edu/ceds/ceds-cmip6-data/
• Emission fluxes are in units of kg m^-2 s^-1 and include NO_x (as NO₂), CO, SO₂, NH₃, 25 speciated VOCs, BC, and OC
• Emission fluxes are provides as monthly averages
• Note: Zip files are group by compound only as a means to reduce the zipped file sizes. The file format for each compound is the same.
