We used 0.9x1.25 horizontal resolution simulation with 56 vertical levels. We use specified dynamics, nudging with 50h relaxation (1%) to MERRA2 reanalysis. Data is saved as instantaneous fields every 6 hours. See a list of saved species. Files are collected as daily information (4 time-slices per file) and are 4.8G each. Data coverage is 2001 to 2017. Anthropogenic emissions are from CMIP6, Biogenic are from online MEGAN2.1, Fire emissions are from QFED. Note that fire emitted DMS 2001-2015 is from CMIP6 and in 2016 and 2017 is from GFAS. CMIP6 2014 anthropogenic emissions are repeated for dates past 2014.
