Emissions and climate effects due to the COVID-19 response Monthly emissions and concentrations for the effects of the Covid-19 pandemic and resulting society response. All scenarios should be compared to the input4MIPS SSP245 baseline We provide sector and national emission files as well as the code to create them from mobility data in Sector csv files have aviation and shipping by nation. National csv files have international aviation and shipping as a separate nation. See for more details. The calculations relating these to the emissions netcdf files can be found at and is detailed in Description of files Monthly emissions of aerosols and precursors are saved directly here, zipped folders contain GHG concentrations and NOx emissions from aviation for the effects of the Covid-19 pandemic and resulting society response. All scenarios should be compared to the input4MIPS SSP245 baseline Five scenarios are given for departures from the SSP2-4.5 baseline. The baseline is also provided for convenience, with timesteps available corresponding to both the 4-year blip and the 2-year blip. Scenarios depart from baseline after the start of 2020. Monthly concentrations of CO2, CH4 and N2O are provided over 2015-2050. For short-lived species emissions are provided for BC, CO, OC, SO2, NH3, NOx, & NMVOCs. Monthly values for years:2015,2019,2020,2021,2023,2030,2040 and 2050 are provided for the four scenarios and baseline (2-year blip, strong and moderate green recovery and fossil fuel recovery). For the 4-year blip nad 4baseline, the years are 2015,2019,2020,2021,2022, 2023, 2025, 2030,2040 and 2050. The SSP245 baseline is also available from the input4MIPS website. NOx emissions from aviation is provided in a zipped folder, with monthly values for years:2015,2019,2020, 2021, 2022, 2023,2030,2040 and 2050. Two files have these years only, (corresponding to 2-year blip and baseline) and two have data for 2024 too (corresponding to the 4-year blip, or baseline for it). Well-mixed greenhouse gas emissions are provided for North, South and global average concentration of CO2, CH4 and N2O for all months 2015-2050 For more info Funding was provided by the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement nos. 820829 (CONSTRAIN) Contact Piers Forster ( for more details.

Version 5 uses data until the end of Dec 2020, and contains a bugfix affecting the results for aerosols and precursors in Dec 2021. Version 5.1 contains a reanalysis affecting aerosols values in Dec 2020.
