Daily aerosol emissions changes in 2020 due to Covid19: modified SSP2-4.5 to account for sector activity level

Daily aerosol emissions estimates for 2020, modified by the country-specific impacts of COVID-19 lockdown.  This repository holds the netcdf files for aerosol and precursor emissions projected by the scenario SSP2-4.5, from the Scenario4MIPs database (https://esgf-node.llnl.gov/search/input4mips/), modified by the country and sector activity levels associated with lockdown for 2020, with observation-based data up until the 5th of July and a fixed estimate thereafter.
