[Wrf-users] very strange results with CLM4 in WRF as compared to NOAH

[Jatin Kala]

Hi,

We've been doing some comparisons of NOAH versus CLM in WRFv3.6, each 
run with 3 different PBL schemes.

Comparisons against observed soundings shows very reasonable results for 
the NOAH runs, but not the CLM runs.

Upon having a closer look at the outputs, there is clearly something 
going wrong within the sponge zone for CLM runs.

See attached. These are identical WRF runs, except for the choice of LSM.

While i do expect some discontinuity within the relaxation zone, the CLM 
outputs is just not physically plausible.

Has anyone encountered similar issues with CLM in WRF?

Cheers,

Jatin
