Run-time I/O question

I'm trying to output the max 10-m wind speed in WRF 4.0. Setting the I/O configuration file to:


results in the following warning:

W A R N I N G : Unable to modify mask for wspd10max. Variable not found. File: wrf_io.cfg at line 1

(The first two fields are output okay.) I also get the same warning for SPDUV10MAX. Thanks.

Can you attach your namelist.input file, in addition to your run log (e.g. rsl.error.0000) so that I can take a look?
Here you go.

According to the registry, It looks like the variable wspd10max is part of the NWP diagnostics package, which means that you'll additionally need to set nwp_diagnostics = 1 in your namelist to have that output. Similarly, SPDUV10MAX is part of a different package, and therefore you would need to set output_diagnostics = 1 in your namelist. There are a few other namelist options that go along with output_diagnostics. You can find additional information here:

Let me know if you're able to get it working after making these modifications. Thanks!
