[Wrf-users] How can I define the variables to write to wrfrst*?

[Douglas Lowe]

Hi Nikhil,

Thanks for your response. I have already tried 'r' as an option for the runtime control (in the hope it was an undocumented feature) - unfortunately it isn't. If a runtime option isn't available then I'll move onto editing the registry files.

I was hoping, though, that the wrfrst* files would be written out via one of the 25 I/O streams. Would anyone know if it is (and if so, which one it is)?

Thanks,
Doug

i think the easier way to do would be to add 'r' in the registry files for the variables you want to write to the
wrfrst files, or remove 'r' if you dont want certain variable and recompile the model after clean -a.
I am not sure if you can do this during runtime.

from wrf documentation i found this


The available options are:

            + or -, add or remove a variable

            0-24, integer, which stream

            i or h, input or history

            field name in the Registry – this is the first string in quotes. Note: do not include

                                                         any spaces in between field names.


which means you dont have 'r' as an option, maybe you can give it a go, or you might have to dig out how the io_file is read and maybe modify it.

Hi,

I'm trying to make a runtime modification to the variables which are written into the wrfrst* files
(using a text file defined by the "iofields_filename" option in the namelist), however I cannot work
out which data stream the wrfrst* files are written from. Could anyone advise me if this is possible
to do or not, and if it is possible then how should I write my commands to do this?

Thanks,
Doug
