column radiation mode in scam5

Dear all,

I tried to  realize the column radiation mode in scam5 via the variable scm_crm_mode = .true. in cam_inparm. But it failed to run with the error as follows. I cannot figure out the reason. Hope somebody can help me. Thank you very much!

(shr_sys_abort) ERROR: diag_allocate: ERROR: allocate failed
(shr_sys_abort) WARNING: calling shr_mpi_abort() and stopping
MPI_Abort: error code = 1001

Meanwhile, I also tried to use PORT (Parallel Offline Radiation Tool) to get the offline radiaiton mode. But it seems not suit for rrtmg in cam5 in cesm1.2. Have someone used PORT to get offline radiation mode of rrtmg?

And if I want to get offline radiaiton code of rrtmg in cam5 or scam5, how can I realize it? Hope someone can give me some advice? Thanks!




I found out some further information, which may not be of much help. The CRM capability in SCAM has not been mainained, and I am not sure we have a released version of the model with PORT fully operational I do not think we do.

Sorry about that.

In terms of documentation, there is an out-of-date wiki:
and, of course, the paper which describes its science:

PORT with FDH/RRTMG/MAM functionality is checked into the CAM 
development trunk and is included in latest few beta versions of CESM: but I think this post dates what has been released.



Thank you very much for the information you provided. It seems I have to seek other method.
