  "abstract": "<p><strong>Emissions and climate effects due to the COVID-19&nbsp;response</strong></p>\n\n<p>Monthly emissions and concentrations for the effects of the Covid-19 pandemic and resulting society response. All scenarios should be compared to&nbsp;the input4MIPS SSP245 baseline&nbsp;<a href=\"https://esgf-node.llnl.gov/search/input4mips/\">https://esgf-node.llnl.gov/search/input4mips/</a></p>\n\n<p>We provide sector and national emission files as well as the code to create them from mobility data in national_level_lockdown_analysis.zip.&nbsp;Sector&nbsp;csv files have aviation and shipping by nation. National csv files have international aviation and shipping as a separate nation. See&nbsp;<a href=\"https://github.com/Priestley-Centre/COVID19_emissions\">https://github.com/Priestley-Centre/COVID19_emissions</a>&nbsp;for more details. The calculations relating these to the emissions netcdf files can be found at&nbsp;<a href=\"https://github.com/rlamboll/2dCOVID19Emissions/\">https://github.com/rlamboll/2dCOVID19Emissions/</a>&nbsp;and is detailed in&nbsp;https://gmd.copernicus.org/preprints/gmd-2020-373/.&nbsp;</p>\n\n<p><strong>Description of files</strong></p>\n\n<p>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&nbsp;the input4MIPS SSP245 baseline&nbsp;<a href=\"https://esgf-node.llnl.gov/search/input4mips/\">https://esgf-node.llnl.gov/search/input4mips/</a></p>\n\n<p>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.&nbsp;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, &amp; 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&nbsp;2015,2019,2020,2021,2022, 2023, 2025, 2030,2040 and 2050. The SSP245 baseline is also&nbsp;available&nbsp;from&nbsp;the input4MIPS website.&nbsp;</p>\n\n<p>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).</p>\n\n<p>Well-mixed greenhouse gas emissions are provided for North, South and global average concentration of CO2, CH4 and N2O for all months 2015-2050</p>\n\n<p><strong>For more info</strong></p>\n\n<p>Funding was provided by the European Union&rsquo;s Horizon 2020 Research and Innovation Programme under grant agreement nos. 820829 (CONSTRAIN)&nbsp;<a href=\"http://constrain-eu.org/\">http://constrain-eu.org/</a>&nbsp;</p>\n\n<p>Contact Piers Forster&nbsp; (p.m.forster@leeds.ac.uk) for more details.<a href=\"http://www.climate.leeds.ac.uk\u00a0\"> www.climate.leeds.ac.uk&nbsp;</a></p>\n\n<p>Paper reference is&nbsp;</p>\n\n<p><strong>Forster, P.M., Forster, H.I., Evans, M.J.&nbsp;<em>et al.</em>&nbsp;Current and future global climate impacts resulting from COVID-19.&nbsp;<em>Nat.
