[Met_help] [rt.rap.ucar.edu #68286] History for query regarding data conversion

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Hi John, 
this is query regarding conversion of binary data (grads/ TRMM rainfall) to the netcdf. 
1. How the TRMM data can be converted into NETCDF. 

2. I have to use the copygb tool. (my model Fc is in netcdf n observations in binary format) 
will copygb too run on NETCDF or grib1????

I am looking for using grid stat tool for further analysis. 

Can U guide me.

Geeta,

I see that you're writing asking about TRMM data.  Please take a look
at
this page:
   http://www.dtcenter.org/met/users/downloads/observation_data.php

On there we list links to TRMM binary data as well as an R-script that
can
read the binary data, subset it, and write a NetCDF file that the MET
tools
can read.  Please note that this script is not interpolating the
values,
just selecting a subset of the data.

The copygb tool only operates on data in the GRIB1 format.

To compare model output to TRMM data, I'd suggest running that R-
script to
select out a subset of the TRMM data that covers your region of
interest.
Then run copygb on your GRIB1 model output to regrid it to the 1/4
degree
lat/lon grid on which the TRMM resides.  And then you can run them
through
the MET grid-to-grid tools, like Grid-Stat and MODE.

Hope that helps.

Thanks,
John Halley Gotway

Ok John,
once I convert the TRMM binary data into NETCDF, then I have to
convert that again into grib1.

how that has to be done???

Geeta,

No, I'd suggest the following:

(1) Convert TRMM binary to NetCDF.  Modify the header of the Rscript
to
select out the min/max lat/lon for the region that covers your model
domain.
(2) Run your WRF output through the Unified Post-Processor (UPP) to
create
GRIB1 output files.
(3) Run those GRIB1 output files through copygb to regrid it to
exactly the
same 1/4 degree lat/lon grid that your TRMM data is on.

That would enable you to compare your model output to the TRMM data.

John,
I have R on my windows system.
How can use R on windows system to convert into NETCDF. can you give
me the command???

Geeta,

Sorry no, I've never run Rscripts via Windows.  I do know that that
script (
http://www.dtcenter.org/met/users/downloads/Rscripts/trmmbin2nc.R)
requires
the R "ncdf" library.  You'd need "ncdf" on your system, which
requires the
presence of the NetCDF library.  It looks like there are binary
distributions of NetCDF available for windows, but I've never loaded
them
or run them myself.

The command line for running that script on Linux looks like this:
   > Rscript trmmbin2nc trmm_file nc_file
Where trmm_file is binary trmm file and nc_file is name for the output
NetCDF file.

Sorry I can't be of more help.

Thanks,
John

Geeta,

This looks to be more of a system configuration issue than an actual
problem with the MET code itself.  And it's very difficult to debug
system
configuration issues remotely.  Sorry but I won't be able to be much
help
on this one.

Thanks,
John
