CDO

you can find it here

Thank you for the info.
I have installed the cdo but the grib to nc conversion is not working.
How to proceed from here?!!

Update

have your read this https://code.mpimet.mpg.de/boards/1/topics/7466?r=7986#message-7986 ?

Sir,

I went through the thread and followed your concluding comment. but there is some error. I have attached the image of cygwin terminal.

I added a tar-file in the download-area: https://code.mpimet.mpg.de/attachments/20542/eccodes-share.tar.gz that can be used like this with cygwin:

cd /usr/local
mkdir -p share
tar xzf <path-to-downloaded-eccodes-share.tar.gz>
cdo -g grb2 -chname,topo,orog -topo t.grb2

you have to use UNIX-like paths in the cygwin like

 tar xzf /cygdrive/f/abc/eccodes-share.tar.gz 

Thank you for your reply and help.

the eccodes are extracted and installed now.

and cdo is also installed after running ./cdo.exe along with the mentioned packages.

but it shows cdo command not found, for all the commands.

but

cdo

yes cdo is installed. but while using cdo as command, it shows command not found.

ok, I think I have to come up with some UNIX-basics here (sorry, in case I misunderstood)

1. In order to be able to execute CDO in all directories (using the cygwin terminal) you have to copy the binary into

   /usr/bin

   order

   /usr/local/bin

2. your uploaded image look ok to me. CDO gives a message, that it was called without using an operator and prints its command line help. that's perfectly fine.

so I guess, all you have to do is

cp cdo.exe /usr/local/bin/ 

There is again an error named CDO (abort).

it must be

cdo -f grb2 ... 

cdo -g grb2 ....

There is some eccodes error.

I kept everything in usr/local, but in the ecd eccodes shows some error.

Should i try installing everything again?

I reinstalled every thing again. The error with eccodes is still same.

you extracted the eccodes-tar file into /usr/local, BUT it has to be /usr/local/share - can you move the eccodes directory from /usr/local to /usr/local/share please?

I think I missed this in the other thread ...

Yes it is working.

Thanking for your patience and help.

for conversion of grib to nc the command is cdo -f nc copy ABC.grib ABC.nc (it is working fine)

what is the command to convert .grd file to nc and .h5 file to nc.

Thank you very much.

no problem - finally it turned out to be my mistake, because I missed the share directory in original post. will edit my old post then

thx for your patience, too!

you can set the output format like

• netcdf

  -f nc

• grib1

  -f grb

• grib2

  -f grb2

hdf5 files are not CF-conform, so CDO cannot handle them in general. there are some operators for importing specifically formatted hdf5 (import_cmsaf), but there is no general support for plain hdf5 input/output.

for transforming hdf5 to netcdf I would try using NCL's script: ncl_convert2nc - but in fact that's just a guess because I usually don't work with hdf5 data.

Thank you for the info.

I am asking about .grd (and not grb). I guess we can convert .grd to .nc using cdo in cygwin. I will be thankful if you can share the command for the same.

P.S. I will figure out something else for .h5 conversion.

sorry fort the misunderstanding. what is the .grd input format?
