    <description descriptionType="Abstract">&lt;p&gt;&lt;strong&gt;Emissions and climate effects due to the COVID-19&amp;nbsp;response&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Monthly emissions and concentrations for the effects of the Covid-19 pandemic and resulting society response. All scenarios should be compared to&amp;nbsp;the input4MIPS SSP245 baseline&amp;nbsp;&lt;a href="https://esgf-node.llnl.gov/search/input4mips/"&gt;https://esgf-node.llnl.gov/search/input4mips/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;We provide sector and national emission files as well as the code to create them from mobility data in national_level_lockdown_analysis.zip.&amp;nbsp;Sector&amp;nbsp;csv files have aviation and shipping by nation. National csv files have international aviation and shipping as a separate nation. See&amp;nbsp;&lt;a href="https://github.com/Priestley-Centre/COVID19_emissions"&gt;https://github.com/Priestley-Centre/COVID19_emissions&lt;/a&gt;&amp;nbsp;for more details. The calculations relating these to the emissions netcdf files can be found at&amp;nbsp;&lt;a href="https://github.com/rlamboll/2dCOVID19Emissions/"&gt;https://github.com/rlamboll/2dCOVID19Emissions/&lt;/a&gt;&amp;nbsp;and is detailed in&amp;nbsp;https://gmd.copernicus.org/preprints/gmd-2020-373/.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Description of files&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;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&amp;nbsp;the input4MIPS SSP245 baseline&amp;nbsp;&lt;a href="https://esgf-node.llnl.gov/search/input4mips/"&gt;https://esgf-node.llnl.gov/search/input4mips/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;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.&amp;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;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&amp;nbsp;2015,2019,2020,2021,2022, 2023, 2025, 2030,2040 and 2050. The SSP245 baseline is also&amp;nbsp;available&amp;nbsp;from&amp;nbsp;the input4MIPS website.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;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).&lt;/p&gt;

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

&lt;p&gt;&lt;strong&gt;For more info&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Funding was provided by the European Union&amp;rsquo;s Horizon 2020 Research and Innovation Programme under grant agreement nos. 820829 (CONSTRAIN)&amp;nbsp;&lt;a href="http://constrain-eu.org/"&gt;http://constrain-eu.org/&lt;/a&gt;&amp;nbsp;&lt;/p&gt;

    <description descriptionType="Other">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.</description>
