Notes
NOAA website for "Science on a Sphere": http://sos.noaa.gov/index.html.
The current web interface works in the latest versions of the Firefox and Google Chrome browsers.
As an aside, I should mention that you can "grab" the sphere image in the right window with your computer's mouse, and turn the image about to look at it from different angles; the little "reset position" button underneath the window returns the sphere to its original viewing position.
