Source code
Get the pre-compiled code, if you want to .
/scratch01/tutuser00/2011WRF_tutorial/WRFDAV3/var/scripts/gen_be/gen_be_wrapper.ksh is the main script that will be used in this practice.
Gen_be consists of several stages. Quite a few executables and scripts are used for the whole process. They are listed below for your reference. These executables and scripts will be called subsequently by the main gen_be_wrapper.ksh.
Choice of your working directory
We recommend running each session in a separate directory, so that it will be easier to check for the necessary input files and look for what output files are created after a successful run.
We recommend you create ~/gen_be directory and enter there to be your working directory for this session.
Edit gen_be_wrapper.ksh
Copy gen_be_wrapper.ksh to be in your working directory.
> cd ~/gen_be
> cp /scratch01/tutuser00/2011WRF_tutorial/WRFDAV3/var/scripts/gen_be/gen_be_wrapper.ksh ./gen_be_wrapper.ksh
Pay special attention to the following settings:
export WRFVAR_DIR=/scratch01/tutuser00/2011WRF_tutorial/WRFDAV3
export START_DATE = 2007091500 # the first perturbation valid date
export END_DATE = 2007091700 # the last perturbation valid date
export NUM_LEVEL = 27 # e_vert -1
export BIN_TYPE = 5
export BE_METHOD=NMC
export FCST_RANGE=12
export FC_DIR =/scratch01/tutuser00/DA_Input_Data/gen_be
export RUN_DIR =/home/tutuser##/gen_be
export DOMAIN = 01
export FCST_RANGE1 = 24
export FCST_RANGE2 = 12
export INTERVAL = 12
export STRIDE = 1
Run gen_be_wrapper.ksh
> ./gen_be_wrapper.ksh
Check output
be.dat is the main output under working directory.
Check log files for each gen_be stage.
Don't know if you are successful ? see the reference log file
Other practice
If this was successful, continue to try more single ob tests using the be.dat you have created.
