[Wrf-users] SOIL temperature initialization

[Pirovano Guido (ERSE)]

Dear WRF users,
we are performing some tests on Land Surface scheme with WRF 3.0.1.1
Our analysis come from ECMWF data having:
0-7 cm
7-28 cm
28-100 cm
100-255 cm 
soil moisture and Temperature fields
 
USing Noah LSM (option 2) real seems able to correctly interpolate
metgrid fields to wrf soil fields,
but using Pleim-xiu LSM we get the following message from rsl.out:
 
.---------
d01 2005-01-10_00:00:00 No 10-40 cm or 40-100 cm soil temperature data
for grid%em_tmn
 d01 2005-01-10_00:00:00 Using 1 degree static annual mean temps
 LAND  CHANGE =             0
 WATER CHANGE =             0
 error in the grid%tmn
 i,j=            1            1
 grid%landmask=    1.000000
 grid%tsk, grid%sst, grid%tmn=    282.5695        0.000000
0.000000
 error in the grid%tmn
-----
 
looking at module_initialization code it seems that using PX scheme the
"0070028 - 0280100 etc.." 
layers structure is not taken into account to define WRF soil
temperature fields, hence
the static annual temp is used.
 
Have you got any suggestion about this issue?
 
thank you in advance
kind regards
 
guido
