No sooner than this was done that the satellite was repositioned, and we had to tweak the calculations a little.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">I've attached the NCL scripts that Rick created, and the plot it generates.
