Right, I know all this already. I'm just making the point that having
the image viewable directly in WWW would be a snap, as opposed to
having to grab the file by ftp, put up a viewer, etc. I never could
get Ken's automatic download script to work on our SunOS system, and
is it really worth 8 hours of my time to debug awk expressions...eh,
I'll pass. Not that you don't write lovely awk, Ken, really! :)

Thanks for this lead!

True. The polar orbitar pictures have more resolution, but we only get a
relevant one once every 8 hours or so.
Actually, the fog cover by itself doesn't tell you much. Rmemeber its
the low pressure in the valley that sucks the fog in. That's what
causes the wind. It's just that in many cases where the valley is
sucking the strongest, the fog tends to get sucked in. So you can use
the fog as a visual clue to pressure differentials. But there are also
days when there is fog on the coast and no low pressure inland, and on days
like that the fog tells you nothing at all about the wind.
