Country level fluxes are provided in three formats: 1. comma-separated values (CSV) file, pilot_topdown_CO2_Budget_countries_v1.csv; 2. Network Common Data Form (NetCDF) file, pilot_topdown_CO2_Budget_countries_v1.nc; 3. Microsoft Excel worksheet, pilot_topdown_CO2_Budget_countries_v1.xls. Grided 1 x 1 degree fluxes are provided in one format: 1. Network Common Data Form (NetCDF) file, pilot_topdown_CO2_Budget_grid_v1.nc These files contain annual net fluxes of CO2 for a six-year period (2015-2020), including: net carbon exchange (NCE), fossil fuel emissions (FF), and lateral fluxes due to crop trade, wood trade, and river export. Please see the data description paper for additional details. DATA POLICY These data are provided for use in scientific research.
