My suggestion is that this is being caused by the non-standard path of the file that is being specified, i.e., E:\work@home\data\IMD_monsum_rf.nc

The component at play here, NCO, does not play well with Windows in my experience, as it's primarily a tool developed for use on Linux and the developers typically don't do much testing on Windows.

I suggest trying using the input file in a different location. Also, try using forward slashes rather than backslashes. For example:

C:/Users/Pawan kumar/data/IMD_monsum_rf.nc

Like NCO this package has been developed for Linux users but we strive to support Windows as well. If you want to send a link to your file I can try to reproduce and debug this error on a Windows laptop.

Hi Pawand, were you able to correct this error. I also have same issue.
