Started a new case - Jobs failing


I am a new user of CESM. I am using it for WACCMX outputs. 

I just created a new case on cheyenne as follows-


./create_newcase --case ~/cases/cheyenne/f.e20.FXSD.f19_f19.001 --compset FXSD --res f19_f19  --run-unsupported

2. ./case.setup

3. ./

4. ./case.submit

The job runs! This is for 2000-01-01

However the problem arises when I try to change the Start date of the run in env_run.xml file, say - <entry id="RUN_STARTDATE"value="2002-03-18">.

I get an error saying - FIND_TIMES: Failed to find dates bracketing desired time.

I am attaching the log file here. Any help will be appreciated. Please let me know if I am missing any input file or failing to change any variable in the env_run.xml



The "SD" in the FXSD compset means that it is nudged with specified dynamics (winds and temperatures). When you change the start date, you also need to change the inital meteorological data file. You can see the default values for nudging as the namelist variables that begin with "met_" in CaseDocs/atm_in:

> grep met_ CaseDocs/atm_in 

 met_data_file          = '2000/'

 met_data_path          = '/glade/p/cesmdata/cseg/inputdata/atm/cam/met/MERRA'

 met_filenames_list             = '/glade/p/cesmdata/cseg/inputdata/atm/cam/met/MERRA/CCMI_sd_filenames.txt'

 met_fix_mass           = .true.

 met_qflx_factor                = 0.84

 met_rlx_bot            = 45.

 met_rlx_time           = 50.

 met_rlx_top            = 55.

 If you wish to change your start date to 2002-03-18, you need to change the initial file by putting the following line in your user_nl_cam file, where you can make changes to the atm_in namelist:   

 met_data_file          = '2002/'
