Output only set of variables in defined area

[janac4]

Hello,
I want to study precipitation and visibility variables at 5 minutes time step. I have followed "Run-Time IO" of the User Guide to successfully output new files every 5 minutes with my selected variables. However, I just need this precision in a small domain of my grid, is it possible to define the domain of interest in the namelist? It is a subdomain of my default wrfouts, but I don't want to change my main files.
I also thought about using time series output with "tslist" file containing my points of interest. However I don't understand how am I supposed to tell WRF which variables I want in the time series. Is there a predefined set? Can I modify it?
Any help will be helpful,
Thanks

WRF has no capability to output variables over a 'subset' of its domain.

I also thought about using time series output with "tslist" file containing my points of interest. However I don't understand how am I supposed to tell WRF which variables I want in the time series. Is there a predefined set? Can I modify it?

You need to have the file 'tslist' in the directory where you run wrf.exe. The format of this file is described here.
Variables included in time series output are prescribed. Please see WRF/run/README.tslist for details.
if you want to change variables included in time series output files, you need to modify the code "share/wrf_timeseries.F". Those variables included in the time series output file can serve as a good example for you to add/delete variables.

Any help will be helpful,

Thank you for your reply,
If I was to modify share/wrf_timeseries.F should I recompile again the WRF model?
Also, these selected variables are superficial? Could I use tslist to output column data in single point?

Yes please recompile WRF after you modify the code.

Those variables that can be output are predefined. The output includes column data at the point you specified in tslist.
