[Wrf-users] WPS: ref_lat problem

[Elsa Tejada]

To whom may it concern,

I am trying to run WPS for a certain area of Europe and North of Africa 
but I have a problem. I set the variables *ref_lat* and *ref_lon* in the 
center of the area, *44.25N 11.25E*, however the output file is not 
centered on that point: the longitude is perfect but the latitude 
variable goes from 10.8N to 65.7N, so the center is *38.25N* instead of 
44.25N.

This is my namelist.wps file

&share
  wrf_core = 'ARW',
   max_dom                    = 1,
   start_date                 = '2014-10-06_03:00:00',
   end_date                 = '2014-10-06_06:00:00',
   interval_seconds           = 10800
  io_form_geogrid = 2,
/

&geogrid
   parent_id                  = 0,
   parent_grid_ratio          = 1,
   i_parent_start             = 1,
   j_parent_start             = 1,
   e_we                       = 1024,
   e_sn                       = 1024,
   geog_data_res              = '2m',
   dx                         = 6000.0,
   dy                         = 6000.0,
   map_proj                   = 'mercator',
   ref_lat                    = 44.25,
   ref_lon                    = 11.25,
   truelat1                   = 44.25,
   truelat2                   = 60.0,
   stand_lon                  = 0,
  geog_data_path = '/home/Build_WRF/WPS_GEOG'
  opt_geogrid_tbl_path = '/home/Build_WRF/WPS/geogrid/'
/

&ungrib
  out_format = 'WPS',
  prefix = 'FILE',
/

&metgrid
  fg_name = 'FILE'
  io_form_metgrid = 2,
  opt_metgrid_tbl_path = '/home/Build_WRF/WPS/metgrid/'
/

And  the geogrid.log file is attached.

I would like to know which is the problem, why the result is not 
centered on ref_lat. Is it a projection problem, or related to ref_x 
ref_y variables... ?

Thank you very much,
Kind regards.
