We have developed simulation output that is intended to be used as boundary conditions for regional modeling. We used CAM-chem at 0.9x1.25 horizontal resolution simulation with 56 vertical levels. Meteorology is driven by specified dynamics, by 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). Data coverage is January 2001 to June 2018. Anthropogenic emissions are from CMIP6, CMIP6 2014 anthropogenic emissions are repeated for dates past 2014. Biogenic emissions 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.

  • Data Format: netCDF
  • File size: 4.8 GB per day (4 x 6-hour time slices per day)
  • Data coverage: January 2001 to June 2018

*** NOTE: The current version of output has incorrect HCN and O3S, please disregard these species ***
