2.  Seeing this error, I changed my data file (input_new.txt) attached  in which I removed the top string
but still the the dots/markers are not plotted. 

3. Sending the script and the input files. 

pls suggest. 
thanks Geeta.

 Hi Geeta,
the error message is telling you what is wrong - type mismatch in gsn_add_polymarker. 
Take a look at the gsn_add_polymarker function page:http://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_add_polymarker.shtml
gsn_add_polymarker wants to have a numeric type for x and y (in your case lon and lat).
function gsn_add_polymarker (
		wks  [1] : graphic,  
		plot [1] : graphic,  
		x    [*] : numeric,  
		y    [*] : numeric,  
		res  [1] : logical   
	)

	return_val [1] :  graphicIn your script the lat and lon arrays are defined as strings but gsn_add_polymarker expects a numeric type. Use tofloat() function for lat and lon conversion.
Bye,Karin
