Re: Attach lat/lon to variables

Thanks, Mary

Actually since I sent the email, I've decided to include national
boundaries, which would use a mapping overlay right? Then I would be
able to use the lat2d/lon2d? I've been looking at all the contour
overlay example to try and figure this out.
I used to use the wrf_contour functions, but I didn't like that it set
some resources internally that made it difficult to change some things.

In my script, lat and lon are 2D arrays with correct unit notation (degree_east,degree_north). They are the same size as the variables I am trying to attach them too. I've used various print statments to make sure of this. Attached is my NCL code.
