how to run cesm2 cam chem with geos-5

[anushree]

hello everyone,
My model CESM2 is not running with geos5 data for cam6-chem.
This is my user_nl_cam file:

ncdata ="/home/cesm/inputdata/atm/cam/inic/fv/fgeos.e12_rel07_chem.FSDSMAM.f19.f19.relv1.cam.i.2006.1x_56L.nc"
bnd_topo = '/home/cesm/inputdata/atm/cam/topo/USGS-gtopo30_0.9x1.25_remap_GEOS5_c02062014.nc'


&metdata_nl

met_data_file = 'GEOS5_09x125_20121001.nc'
met_data_path = '/home/cesm/GEOS5_data_1deg/'
met_filenames_list = '/home/cesm/GEOS5_data_1deg/GEOS5_file_0903_2017_09x125.txt'

do i need to make any other changes?
PLease help me out.

Please see the CAM6 User's guide:

6. Customizing CAM runs — camdoc documentation

You have to change the number of levels you are using in the env_build.xml in CAM_CONFIG_OPTS and add -nlev 56 and also change the calendar to "GREGORIAN"

You can also find more information on our wiki page: Home - CAM-Chem - wiki.ucar.edu

Hi tilmes,
The CESM version I use is 2.1.3, and the compset is FC2010climo. An error occurred when I tried to use the offline method, below is the message.
build-namelist: ERROR: CISM currently only supports a NO_LEAP calendar
CISM currently only supports a NO_LEAP calendar
Either change the calendar to NO_LEAP or create a case without CISM.
(For the latter, you can use SGLC in place of CISM if you don't care about ice evolution. Besides not getting CISM diagnostics, this will just result in slightly different glacier cover in CLM.
Is there a good way to solve this problem without changing the compset？
Thanks in advance！
