Hello everyone!
I tried to change my input boundary datasets, but failed.
I'm using CESM 2.1.3 and the FC2000climo compset, and I want to run two experiments. This is what I did:
I ran the case for a year for spin-up, and then ran the two branch cases :
1) I turned the chemistry off ("-chem none") followed by Colleen's post: Hybrid Run in CESM2.1.3 Model Run error.
(CAM_CONFIG_OPTS: -phys cam6 -chem none)；user_nl_cam(1) attached. Then I ran the branch case for 30 years from 0002-01-01, and it worked with chemistry off.
2）Then I cloned a new case with chemistry off, but using the modified boundary file "ntp_topo.nc"('ntp_topo' means I removed the Himalaya mountains); user_nl_cam(2) attached. Then I ran the branch case from the 0002-01-01 for the same time. I've checked the log file and I'm sure the correct files was being used: grep topo atm.log.9710005.220504-235523
However, the output files from the two experiments are exactly the same. I've checked again by using "ncdump -h"，and global attributes shows "topography_file = "using /public1/home/amduan/panzl/f.21.fc2000.nochem/ntp_topo.nc"". But the variables of the second experiment are totally same as the first one, which means the orography file wasn't changed. It seems I changed the dataset but actually it didn't work.
For example, ncdiff -v U file1, file2, file3, and then both min and max of variables in file3 is 0. (file1 is from the first experiment and file2 the second one, file3 = file1-file2)
I've also changed the orography file but I didn't changed the chemistry, and the results are obviously different.
So, how can I change the orography file while turning the chemistry off?
Thanks for any help!
