import_binary

Added by Abdoulaye SARR over 13 years ago

I am using cdo to convert grads files to netcdf using import_binary command.
The problem is my grads files have 120 variables and the created netcdf file has only 111.
Is there any limitation in number of variables or where is the problem.
Any hint appreciate.

Best Regards,

Abdoulaye

Another question, is it possible when importing to indicate a selected list of variables from the ctl file.

Sorry, I can't reproduce this problem. Could you please give us access to your binary file?

Cheers, Uwe

Thanks Uwe,
It is a big file, unless I try to extract one time step and send it to you.

Please find attached the file

RE: import_binary - Added by Abdoulaye SARR over 13 years ago

unfortunately the bz2 tar file is 53Mo.

Hi Uwe,

I attach a file with the same parameters

d1test.tar.bz2 (18.2 MB) d1test.tar.bz2

RE: import_binary - Added by Uwe Schulzweida over 13 years ago

Hi Abdoulaye,

Thanks! The variable description section in the ctl file d1_test.ctl has 112 entries.
And I got also a file with 112 variables if I import this file with CDO import_binary:

cdo -f nc import_binary d1_test.ctl d1_test.nc
Here is the result of CDO sinfo:

cdo sinfon: Processed 112 variables over 1 timestep. ( 0.00s )

RE: import_binary - Added by Abdoulaye SARR over 13 years ago

Thanks Uwe,

I think the problem come with structure of vertical grid which has 3 generic level as show in the sinfo file and grads didnot see
a few parameters which are in the netcdf file.
Is it possible with cdo to select only a few parameter with full vertical level as in generic level_2?
Another difference when I use sinfo I have numbers not the name of the parameters as in your sinfo. How to have names?

RE: import_binary - Added by Uwe Schulzweida over 13 years ago

sorry, that was a typo, I used sinfon for the output with parameter names.
You can select all variables on the second vertical axis with "selzaxis,2":

cdo -f nc import_binary d1_test.ctl d1_test.nc
cdo selzaxis,2 d1_test.nc d1_test2.nc

RE: import_binary - Added by Abdoulaye SARR over 13 years ago

Thanks Uwe,

I was just wondering if it is possible to change the lev_2 attributes to something more common like levels.
I am using it on a program that don't recognize this lev_2 instead of having the parameter written as (time,lev_2,lat,lon) I want it to be (time,levels,lat,lon).

The question is it possible to change lev_2 by levels?
