Hey at all I have a question regarding the atmosphere namelist of the "BRCP85BPRP" simulation. There are transient Lower Boundary Conditions defined as well as a CO2 Flux File from fossil fuels. I do not understand how CO2 is evolving in this case. Is the CO2 value fixed / ramped at the surface or is the CO2 lower boundary condition overridden by the CO2 Flux file? Extract from the atm_in file: &chem_surfvals_nl bndtvghg= '/cluster/work/climate/cesm/inputdata/atm/cam/ggas/ghg_rcp85_1765-2500_c100203.nc' co2vmr= 0.000001e-6 scenario_ghg= 'RAMPED'

&co2_cycle_nl co2_flag= .true. co2_readflux_fuel= .true. co2flux_fuel_file= '/cluster/work/climate/cesm/inputdata/atm/cam/ggas/co2flux_fossil_RCP85_2005-2100-monthly_0.9x1.25_c20101013.nc'
Thank you very much for clarification! Tom
