Re: lidar plot

Hi Lin,

You are passing more arguments to gsn_csm_pres_hgt than what it
expects. It looks like you are trying to pass two data arrays: ld2
and DUSTAOD. This routine only wants one data array.

Neither one of these are going work anyway, because you need to have a
"lev" coordinate array associated with the leftmost dimension of your
data in order for gsn_csm_pres_hgt to work.

Please see example 8 at:

    http://www.ncl.ucar.edu/Applications/coneff.shtml

and notice how the "lev" array is set up with:

   pres3d = (/1000,950,800,700,600,500,400,300,200/)
   pres3d_at_units= "mb"

   uint= ...
   uint!0 = "plev"
   uint&plev = pres3d

You will need to do something similar. Sorry I don't have more details;
I have to run off to a meeting and then some errands.
