Hi Dennis,

I have put my ncl code and the HDF file I am using in the code in the incoming ftp directory.

Thanks.
Vani.

As noted
   http://www.ncl.ucar.edu/Applications/text.shtml#ex10
which removes overlapping strings is not what you want.
So, I think some form of manual, movement is required.
See untested change below. You will likely have to play
with the dlat and dlon offsets.

Good Luck

   nsta = dimsizes(stations)
   dlat = new(nsta, "float","No_FillValue") ; lat offset
   dlon = new(nsta, "float","No_FillValue") ; lon offset
   dlat = 0.0 ; default is no offset
   dlon = 0.0

   do ns=0,nsta-1
      if (stations(ns).eq."413284") then
          dlat(ns) = -0.005 ; move down some small distance
          dlon(ns) = 0.0 ; no change
      end if
      if (stations(ns).eq."413285") then
          dlat(ns) = 0.005 ; move up some small distance
          dlon(ns) = 0.005

Change above to:

   gsn_text(wks,map," " + station1,(lon+dlon),(lat+dlat),txres)

Hi,

I am new in using NCL scripts. I am trying to plot total attenuated backscatter from CALIPSO data using NCL. I want to plot similar to the CALIPSO browse images (Please see the attached image). Could somebody help me in this. That will very great.

Thanks.
Vani.
