meta data

Dear NCL users,

I'm trying to plot height fields instead of geopotential ones, so I do
the following

plot = gsn_csm_contour_map_ce(xwks, *geo( 0, 22,
{-55:15},{270:330})/10*, res)

however, ncl gives warning messages:

(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 equal to one of the following values:
(0) 'degrees_north' 'degrees-north' 'degree_north' 'degrees
north' 'degrees_N' 'Degrees_north' 'degree_N' 'degreeN' 'degreesN'
(0) check_for_lon_coord: Warning: Data either does not contain a
valid longitude coordinate array or doesn't contain one at all.
(0) A valid longitude coordinate array should have a 'units'
attribute equal to one of the following values:
(0) 'degrees_east' 'degrees-east' 'degree_east' 'degrees east'
'degrees_E' 'Degrees_east' 'degree_E' 'degreeE' 'degreesE'

and the fields are wrong. Is there a way to put all meta data
(coordinates, units, etc) into a new variable in a mathematical
operation ( X = Y/10 ) or I should give them manually?

Thanks
Mateus
