Model Problems

Common problems that have to be dealt with when using the coupled system.

This changes are performed at run time, and the files can be found in

/vol/msverify/sms/USERNAME/JOBID/
For example : /vol/msverify/sms/rg6/b06h/


Problem (b06e) FIXED - ECMWF reverted to old library

Bus errors at the "mmcalc.multiyear.exe" steps of mm_sfc and mm_ua

Recents upgrades had led to incorrect PATHS begin defined for libfortran.so.

Solution

Add the following line to "mm_create_ua" and "mm_create_sfc" in /vol/msverify/sms/rg6/b06e/include. Should be inserted befor first "mmcalc.multiyear.exe" call:
export LD_LIBRARYN32_PATH=/scratch/us/usl:/usr/local/apps/Magics/current/lib:/usr/local/lib32:/lib32:/usr/lib32   


Problem (general, in forecast mode)

Missing fields requested in /include/mm_create_sfc and ocsfc.sms.

Problem occurs in archive->ocsfc and process->mm_sfc

Solution
       
Change multiple instances of 
param     = 229/230/231/232/233/245, 

to
param     = 229/233/245,    


Problem/Solution (general, in forced analysis mode)
 
When providing daily forcing fields, remember to create the file with n+1 days. 
For example, if the forcing ends on October 31, the system also requires November 1 values for interpolation.

Problem (general, in forecast mode)

Need to set OCODBROOT to a local database. There is no way to set this via IFS. 

Solution
   
Edit /include/ocean.h and set the following at the appropriate line
OCODBROOT=/home/ms/gb/rg6/seasonal/newodb

Note: For another user, the directory structure for the ./seasonal database would need to be created before a run
