[gradsusr] write in netcdf format

[lpasmanoranjan]

Dear Jha and Dash,
CDO does not work!! I am getting the following error:

$> cdo -f nc import_binary data.ctl data.nc
Open Error: Unknown keyword in description file
--> The invalid description file record is:
--> pdef 38 28 lcc 46.00 5.00 19.00 14.00 30.00 60.00 5.00 60000. 60000.
The data file was not opened.
cdo import_binary (Abort): Open failed!


Dear Mahakud,
As per your suggestion, I can save only one variable at one level with x
and y varying. How about varying the Z-dimension?

Thank you Jha, Dash and Mahakur for your prompt suggestions.
