[Wrf-users] Noah LSM module (Flerchinger USEd in NEW version)

[Atsuyoshi MANDA]

Dear WRF users and developers,

I am having a problem with Noah land surface model. I got the following 
errors (technically warning) and the model blew up in a short time:

Flerchinger USEd in NEW version. Iterations= 10

I learned that this is related to the problem with calculation of the 
the soil liquid moisture content, from the following websites:
http://forum.wrfforum.com/viewtopic.php?f=6&t=2531
http://stupidcomputerhints.blogspot.jp/2011/04/compendium-of-wrf-errors.html

I have checked the soil moisture data in my met_em files and they look 
OK. To figure out what went wrong, I would like to output latitudes and 
longitudes of the grid points where the computation of soil liquid 
moisture content fails.

Is it correct to add the line shown below to the subroutine FRH2O in 
WRFV3/phys/module_sf_noahlsm.F?


         IF (KCOUNT == 0) THEN
             PRINT *,'Flerchinger USEd in NEW version. Iterations=',NLOG

!===========================================================
             print *, grid%xlat (iloc,jloc), grid%xlat (iloc,jloc)
!===========================================================
.................................
.................................
! ----------------------------------------------------------------------
! END OPTION 2
! ----------------------------------------------------------------------
         END IF


Of course, I understand I must add the arguments grid%xlat, grid%xlat, 
iloc, and jloc to the subroutine FRH2O before adding the line above.

I am not quite sure which variables I should use for iloc and jloc. I 
guess they should be spatial indices of the whole domain.

Thank you very much in advance.

Best regards,
Atsuyoshi
