[ncl-talk] exact location of a lat/lon coodrinates in the grid-box

[Athanasios Karagiannidis]

Dear sirs/madams

I have a question that I’m going to formulate it using an example:
Let’s say I have a dataset (Lat, Lon, T). The grid is 1x1 degree. One of the many points may be Lat=20, Lon=20, T=10.
The question is: When ncl draws a map of T, what does the Lat=20, Lon=20 represents? The center of the 1x1 degree grid-box? Or maybe a corner? For example, if Lat=20, Lon=20 is the southwest corner of the 1x1 grid-box, then the center of the grid-box is at Lat=20.5, Lon=20.5.

Kind regards
