Error in User's Guide

[meteoadriatic]

Good day all,

In "Namelist Variables" section of the User's Guide, under &diags section, there is this Note:

To output fields on pressure levels, the following variables must also be set. For example,
auxhist23_outname='wrfpress_d<domain>_<date>' (modify output stream and file name accordingly)
io_form_auxhist23=2 (2=netCDF file format)
auxhist23_interval=180,180 (interval in minutes for each domain)
frames_per_auxhist23=1,1 (number of files output per interval period)

However, all those parameters are "22", not "23". So:
auxhist22_outname
io_form_auxhist22
auxhist22_interval
frames_per_auxhist22

Have a nice day,
Ivan

Hi Ivan,
Per the code in WRF/share/module_check_a_mundo.F, for pressure level diagnostic output, the stream should be 23. Can you let me know what information you are using that tells you that it should be 22, instead of 23? Thanks!

Good day,

If you run the model with '23s', it crashes immediatelly, telling you that those must be '22s'

Take a look; with these settings:

 auxhist23_outname             = 'agl_d<domain>_<date>',
 io_form_auxhist23             = 2,
 auxhist23_interval            = 360, 15,
 frames_per_auxhist23          = 1, 1,

...

 &diags
 z_lev_diags                   = 1,
 num_z_levels                  = 9,
 z_levels                      = -60, -80, -100, -120, -140, -160, -180, -200, -220
 solar_diagnostics             = 1,
 /

result is this:

taskid: 0 hostname: wrf04

If I change all those four to 22, everything works as intended:

 auxhist22_outname             = 'agl_d<domain>_<date>',
 io_form_auxhist22             = 2,
 auxhist22_interval            = 360, 15,
 frames_per_auxhist22          = 1, 1,

Thanks for the clarification. You're absolutely correct. It seems that stream 23 is needed with the p_lev_diags option, but when using z_lev_diags options, stream 22 should be used. I made an adjustment in the Users Guide. Thank you so much for bringing this to our attention!
