It doesn't work in changing surface data

[Jie Hsu]

Hi all,

I want to run two B1850 time series experiments use CESM 2.1.4, and I also changed the surface data in one of them, but it doesn't work (i.e., it outputs the same result as the CTR simulation).

I ran two B1850 time series simulations:

Control simulation:
echo "flanduse_timeseries = '/work1/u7719052/surf_data/landuse.timeseries_0.9x1.25_hist_78pfts_CMIP6_simyr1850-2015_c170824.nc'" >> user_nl_clm
echo 'use_init_interp = .true.' >> user_nl_clm
echo "check_dynpft_consistency = .false." >> user_nl_clm
./xmlchange CLM_NAMELIST_OPTS="use_init_interp=.true. init_interp_method='general'"

Experiment simulation:
echo "flanduse_timeseries = '/work1/u7719052/surf_data/landuse.timeseries_0.9x1.25_hist_78pfts_CMIP6_simyr1850-2015_c170824_DEFOREST.nc'" >> user_nl_clm
echo 'use_init_interp = .true.' >> user_nl_clm
echo "check_dynpft_consistency = .false." >> user_nl_clm
./xmlchange CLM_NAMELIST_OPTS="use_init_interp=.true. init_interp_method='general'"

I can't understand why it showed the same total LAI in both CTR and Experiment simulations...


In the "lnd_in" file, you can see that it has already read the time series surface data, so I am not sure why it doesn't work.


Thank you, and I hope someone can help.

Best,
Jie

Another user posted a similar problem, and I gave this response, maybe it will help:

Using my own surface file for CLM

Hi there, I am running multiple experiments to examine the BVOC emissions of different land use change scenarios. Firstly, i made a regridded land surface file based on surfdata_0.47x0.63_16pfts_Irrig_CMIP6_simyr1850_c170919.nc where i replaced UK land cover with higher res info. I have...

make “check_dynpft_consistency = .true” is OK
