problems about aerosoldep input data in RCP4.5 simulation

Hello ! I want to run a RCP4.5 experiment using B_RCP4.5_CN compset with f09_g16 resoluton. My model version is cesm1_2_0.First, I download the restart files (b40.20th.track1.1deg.008) from input data repository. Among the restart files,the atm components initial data is b40.20th.track1.1deg.008.cam2.i.2005-01-01-00000.nc, It is a little difference from modeldefaut setting b40.20th.track1.1deg.008.cam.i.2005-01-01-00000.nc (cam not cam2). So I changed the initial datato b40.20th.track1.1deg.008.cam2.i.2005-01-01-00000.nc in user_nl_cam. The model could build successfully.But when I submited the job, it crashed some time later. I check the log file, the errors are as follows :  trcdata_init: file%has_ps =   T aero dep fluxes are prescribed in :aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc trcdata_init: data type: INTERP_MISSING_MONTHS file: aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc (GETFIL): attempting to find local file aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc (GETFIL): using /ocean2/liurj/inputdata/atm/cam/chem/trop_mozart_aero/aero/aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc open_trc_datafile: /ocean2/liurj/inputdata/atm/cam/chem/trop_mozart_aero/aero/aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc set_time_float_from_date: error return from ESMF_TimeSet for set_time_float_from_date (shr_sys_abort) ERROR: CHKRC  (shr_sys_abort) WARNING: calling shr_mpi_abort() and stopping I check the "time" variable in aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc using ncl script as follows:    f = addfile("aerosoldep_rcp4.5_monthly_1849-2104_1.9x2.5_c100402.nc","r")    time = f->time    YYYY = ut_calendar(time,0)    year = YYYY(:,0)Output of the "year" is not from  1849 to 2104,  I think the last year of the time variable should be 2104 , but it is 1849. Is it right ?I wonder if the errors above mentioned is connected with the "time" variable in the aerosoldep file, and how should I do to solve this problem？ Could some one please give a suggestion about this error, Thanks !

Hi I just sloved the problem this morning. I replaced the input aerosoldep file to "aerosoldep_rcp4.5_monthly_1849-2505_1.9x2.5_c100929.nc". (download from https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/chem/trop_mozart_aero/aero/The "time" variable is correct in this nc file. But I am not sure if this is scientific right. By the way, It don't need to change the atm components initial data in the simulation, I made a mistake.Hopefully It is useful for you.
Good luck !

yes, I just replaced the aerosol deposition file. By checking the two deposition file, I found they have the same value of aerosol deposition. But in the first file, aerosol deposition data is missing after 1904 year, and the "time" variable seems not right. So I replace it by the second file.
Regards
