user_nl_cam problems

[adrianabossolasco]

Hi everyone!I am running CAM5 with MAM7 (FSTRATMAM7) I edit my user_nl_cam file for modify and adding some others emissions file. specifically in the part of external forcing I have:&chem_inparm
ext_frc_cycle_yr               = 2000
 ext_frc_specifier              = 'NO2    -> /scratch/CESM/inputdata/atm/cam/chem/1850-2000_emis/IPCC_emissions_aircraft_NO2_1850-2000_1.9x2.5_c090729.nc',
         'SO2    -> /scratch/CESM/AB_emissions_file_MAM7/VolcanEESMv3.10_SO2_850-2016_Mscale_Zreduc_2deg_c180416.nc',
         'bc_a3  -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam3_bc_elev_2000_c120315.nc',
         'num_a1 -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam7_num_a1_elev_2000_c120716.nc',
         'num_a2 -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam3_num_a2_elev_2000_c120315.nc',
         'num_a3 -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam7_num_a3_elev_2000_c120716.nc',
         'pom_a3 -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam3_oc_elev_2000_c120315.nc',
         'so4_a1 -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam3_so4_a1_elev_2000_c120315.nc',
         'so4_a2 -> /scratch/CESM/inputdata/atm/cam/chem/trop_mozart_aero/emis/ar5_mam3_so4_a2_elev_2000_c120315.nc'
 ext_frc_type           = 'SERIAL'
srf_emis_cycle_yr              = 2000

I try to run a test with this configuration and I get the next failed:Opened existing file
 /scratch/CESM/inputdata/atm/cam/chem/1850-2000_emis/IPCC_emissions_aircraft_NO2

I check the data file for aircraft emissions of NO2 and the data are available for everymonth even for the 2000 year that is the year that I pretend to run. I really apreciate any help! Cheers!

I think the model is confused because you are specifying a cycle year but not to be cyclical, so there is a logical conflict.
