Hi Rich,

I believe this is the info used for the clear sky clocks, with each "clock"
pulling the data from the pixel at its location.

That's exactly right (and put a link just for good measure http://cleardarksky.com/csk/ )
In fact, if you have the luck of seeing a talk by Attila Danko about his CSC (or the even better
Rahill/Danko about both sides, how the forecasts work/how the website works) it's well worth the
trip/registration/expense.

It's inaccurate to state that the CSC only has data from these pages. Darkness isn't derived from the CMC
data and the other nifty links aren't either.

It also has WAP pages so you can get the forecasts for your favorite site from your cellphone. For example see this page: http://cleardarksky.com/cgi-bin/wapclock.py?id=Montreal

While I am sure more can be considered encyclopedic, CSC is as close as it gets to a one stop shopping for astro related info about your observing site
(the darkness take into account moon brightness for instance).
