Four-year blip emissions changes due to COVID-19: modified SSP2-4.5 to account for sector activity level

<p>This repository holds the netcdf files for aerosol emissions projected by the scenario SSP2-4.5, from the Scenario4MIPs database (&nbsp;<a href="https://esgf-node.llnl.gov/search/input4mips/">https://esgf-node.llnl.gov/search/input4mips/</a>), modified by the country and sector activity levels associated with lockdown, projected out for 5&nbsp;years after 2020 before returning to baseline. The details of these activity estimates runs in parallel to those described in&nbsp;<a href="https://github.com/Priestley-Centre/COVID19_emissions">https://github.com/Priestley-Centre/COVID19_emissions</a>, except instead of a 2-year blip, we have done a 4-year blip. Note that it is one year after the blip has finished before things return to baseline.</p> <p>The&nbsp;methodology behind these calculations is based on&nbsp;<a href="https://github.com/Rlamboll/modify_COVID19_netCDF_Emissions/">https://github.com/Rlamboll/modify_COVID19_netCDF_Emissions/</a>, a slight modification of the approach used in&nbsp;<a href="https://zenodo.org/record/3947917#.XxR_qyhKhPZ">https://zenodo.org/record/3947917#.XxR_qyhKhPZ</a>&nbsp;for aerosols emissions. We present only a single scenario (called 4-year blip, featuring a one year recovery after the end of the 4&nbsp;years) compared to the baseline.</p> <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>
