Unable to manipulate GRIB files with CDO

Added by U. Cordier over 2 years ago

Hello,

I am trying to use CDO for an electronic project where I have to select certain types of data from a weather model (AROME HD).

I pretty much managed to install the CDO tool by following this YouTube video. https://www.youtube.com/watch?v=cuB00_xWk-0
I'm on Windows so it complicates things, so I use cygwin.

The install seems to have worked, as I can recognize the .nc files.
On the other hand, I have to manipulate grib files and there it doesn't work.

AzureAD+ordi2113604@PNL-R9131HLL /bin
$ cdo sinfov meteo.grib2
GRIB_API ERROR   :  Unable to find boot.def. Context path=/usr/local/share/grib_api/definitions
grib_context.c at line 216: assertion failure Assert(0)
Aborted (core dumped)

I took a random .nc file and it seems to work.

cdo sinfon: Processed 20 variables [0.06s 12MB]

Can you help me ?

Know that I have never used this kind of tools before and that I am not very comfortable with terminals, so please explain to me so that I understand well.

RE: Unable to manipulate GRIB files with CDO - Added by Karin Meier-Fleischer over 2 years ago

This is an old version, the current version is 2.0.5. Please install the current version.

RE: Unable to manipulate GRIB files with CDO - Added by U. Cordier over 2 years ago

I deleted the cdo.exe file in the bin folder of cygwin. I added the latest version cdo.exe and cygeccodes.dll .
Then I install cdo by doing ldd ./cdo.exe , it seems to work, no error message.

Yet there is a problem, it does not respond to the instructions:

AzureAD+ordi2113604@PNL-R9131HLL /bin
$ cdo -V

AzureAD+ordi2113604@PNL-R9131HLL /bin
$ cdo sinfon meteo.nc

AzureAD+ordi2113604@PNL-R9131HLL /bin
$

I don't know where the problem comes from.

Sorry, but here we need someone working with Windows 10 and cygwin to weigh in.

RE: Unable to manipulate GRIB files with CDO - Added by Estanislao Gavilan over 2 years ago

Hi,

I have not been able to use remapcon in the windows version. Did you try to set a Linux virtual machine? cdo is more friendly in linux environment

Kind regards,

Estanislao

Thanks a lot !

Yes it works after installing an Ubuntu virtual machine.

It's still a pity that there is no functional version of CDO under Windows even though it is the most used OS.
