Re: meteogram

I am not terribly familiar with WRF output. Does zz (z_point) actually
vary with time? If not, then zz could be set up as a 1D array as in the
following:
zz = z_point(bottom_top|:,Time|0)

If zz does vary with time then both vfYArray and vfXArray must have the
same dimension size. (bottom_top x Time) You will then want to set
vfYArray = zz as you are doing now. However, vfXArray is set to be equal
to taus which is a 1D array of times. You will need to convert taus into
a 2D array of the same sizes as z_point/zz. (The times will be the same
for each level.) You can use conform to do this, or set up a quick do loop.
