[ncl-talk] How to add topography in a "transect" cross section

[Lyndz]

Dear NCL experts,

*Problem:*
I am plotting a cross section along two lat-lon points using the transect
example in NCL. My input file has no topography nor hgt variable. I want to
mask the topography since the transect crosses an Island.
Any suggestions on how I can do this in NCL?


*Here's my input file:*
https://www.dropbox.com/s/wt1q4wwnjrg4nvo/q_ein75-RegCM_1998-2005_DJF_1.nc?dl=0


*What I have so far:*
Attached are the script and output images.


I'll appreciate any help on this matter.

Sincerely,
Lyndz
