You can find some general information about our GEM model output here: GEM model output
Full description of the tools below and other tools can also be found on the following page: Looking at RPN files
Having a first glance at the GEM model output
vl3 / vl4 / vl5 → list variable names and descriptions
To list the names (and if lucky units) of the variables inside a file try the command:
Volet |
---|
vl5 rpn_file |
And there are some more variable lists here: Variable dictionaries
voir → list content (names / date/time / level)
To have a closer look at the fields and see date/time, levels, etc. try 'voir':
Volet |
---|
voir -iment rpn_file | less |
For more information about 'voir' check here:

xrec → visualize fields
To visualize the fields you can use 'xrec':
Volet |
---|
xrec -imflds rpn_file |
but But you need to have connected with 'ssh -YC ...' to open windows.
For more information about 'xrec' check here as well:
https://wikienseignement.uqam.ca/display/EDDSDLTEL/Looking+at+RPN+ xrec - documentation
Manipulate RPN files
To extract fields you can use either 'r.diag select ...' or 'editfst'. You can find information about both here:
https://wikienseignement.uqam.ca/display/EDDSDLTEL/Looking+at+RPN+files#LookingatRPNfiles-ManipulatingRPNfiles Manipulating RPN files
But both these tools can be a little tricky to use. So don't hesitate to contact me when you get there!
Convert RPN to NetCDF
In general it would be better to keep GEM output in RPN format to avoid "doubling" the output data. However, in some cases it can be useful to convert files in RPN format to NetCDF
Have a look at the following file on the UQAM servers:
~winger/Scripts/NetCDF_converter/README.txtformat or vice versa.
The tool with which one can do this is called cdf2rpn. You can find information about cdf2rpn under the following link: cdf2rpn - documentation
