Overview:
This is an atmosphere-only compset with perpetual 1850 forcings based on CMIP6 input4mips data. The letter "S" in the name stands for "special" to differentiate from the default atmosphere use case (F1850C5-CMIP6) for the DECK coupled compset A_WCYCL1850S_CMIP6, because some atmospheric settings (e.g., ieflx_opt and initial conditions) are different for the F and A cases.
Ocean Initial Condition:
- Provenance for CMIP6 (DECK) SST and sea ice input data are documented at /wiki/spaces/ATM/pages/201525378
- Download the files from ESGF/input4mips
- File names:
- SSTs: tos_input4MIPs_SSTsAndSeaIce_CMIP_PCMDI-AMIP-1-1-4_gn_187001-201712.nc (md5sum: 'f2baf16f5a40fe53d9d2429e8dd1edf4')
- Sea ice: siconc_input4MIPs_SSTsAndSeaIce_CMIP_PCMDI-AMIP-1-1-4_gn_187001-201712.nc (md5sum: '50d1315023b11fdd011fe74f7ae37b5e')
- Resolution: 1 degree x 1 degree, monthly
- Version: 20180427
- File names:
- The input4MIPs files start from 1870-01-01. Use the climatology of first 10 years (1870-1879) as the prescribed data for the F1850 compset
- The file is uploaded on the E3SM input data server at: https://web.lcrc.anl.gov/public/e3sm/inputdata/ocn/docn7/SSTDATA/sst_ice_CMIP6_DECK_E3SM_1x1_1850_clim_c190125.nc
- The code for generating the file can be found at (place holder for github link)
Land Initial Condition:
- Trying some tests (will be updated when finalized).
Atmosphere Initial Condition:
- Uses the atmospheric state at the end of DECK piControl simulation
- File name: 20180129.DECKv1b_piControl.ne30_oEC.edison.cam.i.0501-01-01-00000_c20190202.nc
