Specifying Z levels

[Andrea Storto]

Hi,
I'll try your suggestion to know what I can get,
even if I don't understand how it could help me,
if I've only U,V,W variables (Components of wind)
and I want to plot, for instance, a W contour in vertical plane
(x-z) keeping real proportions of z levels?!
Think of a stretched grid: the first vertical spacing (at ground level) is
about 30 m, while the last one (a little above tropopause) is
about 300 meters.

Thanks

Andrea
