Initial Request
----------------------------------------------------------------
Sorry the message kind of mix up. This is the last email that I need
help from Paul
Dear Paul
I put the file into Jam_data.
The observation is ST4_2007*
and forecast is WRFPRS_d01_24_30.nc
I try to do 6 hr forecast.
Thank you so much for your help
I do not know why it did not work. it used to work before when I
compared .nc with nc forecast but when I changed grib observ it does
not work

Jam,
I started by plotting your forecast and obs data to compare the
domains. I attached the plot showing the discrepancy
that I found. To fix this, I downloaded the stageIV data from the
website and used the commands shown below to regrid
the data and run grid_stat using both your config file,
GridStatConfig_APCP_6, and your model data file,
WRFPRS_d01_24_30.nc. I figured out which arguments to pass to copygb
by using the example shown in the MET Online
Tutorial
(http://www.dtcenter.org/met/users/support/OnLinePractical/OnLinePractical_611/copygb/run3.php).
Please let me
know if you have questions about these commands.
Paul

Dear Paul
I can run the MET successfully Thank to you but i want to plot themam
out too.
I wonder what program do you use to plot Stage 4 observation data out.
I try to use ncl plot it but it came out the whole domain not regrid
it.
Thanks

Jam,
I use software called Integrated Data Viewer (IDV):
http://www.unidata.ucar.edu/software/idv/. It plots both gridded
NetCDF files and GRIB.

Dear Paul
I got the results to compare observations with model and HSS score
is low.
I think the unit is mismatch.
For the stage IV the unit is kg/m2 and the wrfoutput is mm.
When I was running MET ? Is it the correct automatically or what I
need to do before compare the wrfoutput (mm) with stage IV data
(kg/m2)
Thanks

Jam,
After struggling with some elementary dimensional analysis on early
Monday morning, we confirmed what is also stated at
the link below: 1 kg/m2 = 1 mm. Thus, the units are not the problem.
I would recommend plotting your forecast and
observation data to make sure that they look reasonable.
Thanks,
Paul
