gen_be utility

Issues with running 3DVAR.

gen_be utility

Postby delfida2003 » Tue Feb 03, 2009 1:41 pm

Hi, I'm trying to generate my own BE matrix using gen_be utility as WRF manual v.3 suggest.
I set the following variables in the "gen_be_wrapper.ksh" file

export WRFVAR_DIR=/home/model/IDA/WRFDA
export START_DATE=2008052200
export END_DATE=2008052312
export NUM_LEVELS=28
export REGION=aniene1
export EXPT=expt1
export EXP_DIR=/home/model/IDA/$REGION/$EXPT

and I obtain:

Tue Feb 3 19:40:46 CET 2009 Start
WRFVAR_DIR is /home/model/IDA/WRFDA exported

Stage 1 failed with error 127

Therefore I thought to set some variables in "gen_be_set_defaults.ksh", but I obtain the same error 127 in the stage 1.

Someone can help me?

Thank you

please carefully check the availability of the dataset under /home/model/IDA/aniene1/expt1/fc/, make sure every wrfout is there.

or you can try the START_DATE, 12h later.

I create directory "aniene1" and subdirectories "expt1" and "fc" and then I put my wrfout in "fc" as a directory/files structure:

2008052100/wrfout_d01_2008-05-21_00:00:00
2008052100/wrfout_d01_2008-05-21_12:01:47
2008052100/wrfout_d01_2008-05-21_00:00:00
2008052112/wrfout_d01_2008-05-21_12:00:00
2008052112/wrfout_d01_2008-05-22_00:01:47
2008052112/wrfout_d01_2008-05-22_12:01:27
etc.....

In "gen_be_wrapper.ksh" I also added "export FC_DIR=$EXP_DIR/fc "... without good results!

Based on the log file, you should carefully check the availability of the files, such as:

/home/model/IDA/aniene1/expt1/fc/2008052100/wrfout_d01_2008-05-22_00:00:00
/home/model/IDA/aniene1/expt1/fc/2008052112/wrfout_d01_2008-05-22_00:00:00
/home/model/IDA/aniene1/expt1/fc/2008052112/wrfout_d01_2008-05-22_12:00:00
....

excuse me ,i have got the same error as i run the test case of WRFDA3.1.1, gen_be_wrapper.ksh is like this:
export WRFVAR_DIR=/home/name/Program/WRFDA_V3.1.1
export FC_DIR=/home/name/Program/WRFDA_V3.1.1/var/scripts/gen_be/fc # where wrf forecasts are
export RUN_DIR=/home/name/Program/WRFDA_V3.1.1/var/scripts/gen_be${BIN_TYPE}


that i make a directoy in /home/name/Program/WRFDA_V3.1.1/var/scripts/gen_be,named fc,and it is empty,i donnot know if i should put some file in it.however,i donot have wrfout_d01 in my directory.what should i put in my /fc?
and the error is just like this:

I'm sorry.What's the meaning of your" forcast background"?
I'm appreciated for your answer.
