I take it back, beardedbruce.

"I have a Ba. Sci. in Physics and astronomy, and over 30 years experience in Spacecraft Operations, as well as having been Clementine Data Manager, EO-1 Data Manager, GALEX and IBEX Flight Controller, and Orbit Determination for GLTN (under the Crustal Dynamics Project.)"

I AM impressed.

But the area under discussion falls under the headings of atmospheric science, meteorology, and oceanography.

It's not--ahem--rocket science.
