Trouble with CLM 4

Postby WRF_Climo4 » Tue Feb 18, 2014 3:06 pm

Hello,

I am trying to run the newest version of WRF-ARW with CLM4 as the land-surface model. My simulation is ending right away with no obvious errors, so I can't figure out what's wrong. In the namelist I have sf_surface_phyics = 5 and num_soil_layers = 10...is there something I'm forgetting? If I switch to Noah with everything alse the same it runs fine. Thank you in advance!

(1) if you chose sf_surface_phyics = 5, you should redo real.exe to generate wrfXXX_d01 files.
(2) If you use HPCs, since WRF-CLM needs more cores, you can increase the core number.

Hi,
I think , you should choose num_land_cat 28, if you use USGS lake geogrid date .

HI,

Did you fix your error with CLM4? I got the same problem. Model would be crashed after several hours runs.

I have so many clh GAMMA with Nan values.

clh GAMMA: NaN 0.000000000000000
0.000000000000000 NaN 1.000000000000000
0.000000000000000
clh GAMMA: NaN 1.017322561848549
0.000000000000000 NaN 1.000000000000000

Will that be one of the reason to cause the problem?


Thanks!

Flair
