[ncl-talk] coordinate problem

[Xin Xi]

Hi, I am having a problem with assigning coordinate. Please tell me what I
did wrong. Thanks!

Part of the script:
  lat1d = fspan(lat_ll,lat_ll+lat_res*(numpix_y-1),numpix_y)
  lat1d!0     = "south_north"
  lat1d at units = "degrees_north"
  lon1d = fspan(lon_ll,lon_ll+lon_res*(numpix_x-1),numpix_x)
  lon1d!0     = "west_east"
  lon1d at units = "degrees_east"

  footavg=dim_avg_n(foot,0) ; foot has dims of (ntime, numpix_x, numpix_y)
  footavg!0="south_north"
  footavg!1="west_east"
  footavg at south_north=lat1d
  footavg at west_east=lon1d

  plot = gsn_csm_contour_map(wks,footavg,res)


I GOT THIS ERROR:
(0)    check_for_y_lat_coord: Warning: Data either does not contain a valid
latitude coordinate array or doesn't contain one at all.
(0)    A valid latitude coordinate array should have a 'units' attribute
