'units' attribute of coordinate array

Dear all,

I know it is an old problem but I just couldn't fix it. The error message
is:
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
equal to one of the following values:
(0) 'degrees_north' 'degrees-north' 'degree_north' 'degrees north'
'degrees_N' 'Degrees_north' 'degree_N' 'degreeN' 'degreesN' 'deg north'

My did add this unit and give it to my variable, but it didn't work. Here
is my scripts concerning the problem:
    lat1 = fspan(-65,-75,201)
    lat1@units = "degrees_north"
    lat1!0 = "lat"
    lat1@long_name = "latitude"
    lat1@standard_name = "latitude"
    lat1@axis = "Y"
    print(lat1)

    lon1 = fspan(0,359.95,7178)
    lon1@units = "degrees_east"
    lon1!0 = "lon"
    lon1@long_name = "longitude"
    lon1@standard_name = "longitude"
    lon1@axis = "X"

    c1&lat = lat1
    c1&lon = lon1
    printVarSummary(c1)
    printVarSummary(c1&lat)
    printVarSummary(c1&lon)

; plot
    wks = gsn_open_wks("x11","plot_grid-reg.ncl_bsa_AA")
    plot = gsn_csm_contour_map_ce(wks,c1,False)

I really appreciate it if anyone can give me a clue.
Thank you very much!
Merry Christmas!

Best,
Wenshan
