[ncl-talk] overlay pbl and dust in same height vertical axis

[Dennis Shea]

Also, look at the meteogram page:

meteogram plots are typically attached because they share the time
(abscissa) coordinate.

The GrADS link on the above page is tuned for a particular data set.
However, it is a nice plot and may give you ideas on other variable to plot.
