Re: Wrfout wind profiler scripting

Hi Elliot.
Looking at your script I don't see an array that would house the height
in meters of each sigma level. Sigma levels vary in height, so I'm not
sure what you want to use as your heights. Regardless, assuming you have
an array that houses the heights for each sigma level, I think the
easiest thing for you to do would be to set uv_res@vfYArray = to your
height array. Note that dimensions of your height array would have to
match the bottom_top dimension of your ugrid/vgrid/wspd array.

Hope that helps in some way. If not, let the group know..
Adam
