Emissions changes in 2020 due to Covid19

Emissions and climate effects due to the COVID-19 response

Both sector and national emission files are given as well as the code to create them from mobility data

Sector  csv files have aviation and shipping by nation. National  csv files have international aviation and shipping as a separate nation. See https://github.com/Priestley-Centre/COVID19_emissions for more details

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 https://esgf-node.llnl.gov/search/input4mips/

Four scenarios are given for departures from the SSP245 baseline. The baseline is also provided for convenience. Scenarios depart 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. The SSP245 baseline is also available from the input4MIPS website. 

NOx emissions from aviation is provided in monthly values for years:2015,2019,2020, 2021, 2022, 2023,2030,2040 and 2050. 

Well-mixed greenhouse gas emissions are provided for North, South and global average concentration of CO2, CH4 and N2O for all months 2015-2050

Funding was provided by the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement nos. 820829 (CONSTRAIN) http://constrain-eu.org/
