FATAL CALLED ERROR when ./real.exe for WRF-UCM using NARR

[lslrsgis]

Dear WRF community,

I am trying to use WRF-UCM to do one month simulation around New York city. NARR (0.5*0.5deg, 3h) is used to generate lateral boundary condition and initial condition.

It seems OK when processing NARR files, namely the following four files (taking 2006070115 as example):
merged_AWIP32.2006070115.3D
merged_AWIP32.2006070115.RS.clm
merged_AWIP32.2006070115.RS.pbl
merged_AWIP32.2006070115.RS.sfc

However, when ./real.exe, there is fatal called error:
-------------------------------------------------------------------------------------------
p_top_requested = 5000.00000
allowable grid%p_top in data = 10000.0000
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 1173
p_top_requested < grid%p_top possible from data
-------------------------------------------
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 1173
p_top_requested < grid%p_top possible from data


The namelist files, narr file lists and related files can be found in the tar file. Any help is appreciated, thanks.

The NARR data only go up to 100 hPa, while you've requested a model top of 50 hPa in your namelist.input file. You'll either need to request a model top <=100 hPa in your namelist.input file, or you'll need to use another dataset.

Thanks. I have changed the p_top_requested to 100000. However, when ./real.exe, there is error pompted out as:

What should I do?

 

[lslrsgis]

Moreover, when I start to ./real.exe before the above step, it comes:

----------------- ERROR -------------------
namelist : num_metgrid_soil_levels = 4
input files : NUM_METGRID_SOIL_LEVELS = 0 (from met_em files).
d01 2006-07-12_00:00:00 ---- ERROR: Mismatch between namelist and global attribute NUM_METGRID_SOIL_LEVELS

d01 2006-07-12_00:00:00 ---- ERROR: Mismatch between namelist and input file dimensions
NOTE: 2 namelist vs input data inconsistencies found.

Then I changed the soil levels and metgrid_levels in the namelist.input to consist with met_grid files. I am not sure this is proper or not.

BTW, is there any detailed guide for using NARR in WRF? Thanks.

Thanks for the valuable comments. The problem has been solved.
