Eclipse maps—maps that show the path of solar eclipses across the surface of the Earth—are very much a thing. As I wrote in my first blog post about eclipse maps back in 2010, “These maps are vital to eclipse chasers, who spend vast sums travelling to places where they can see one, and those slightly less insane who nevertheless are interested in when the next one comes around.” Eclipse chasers are already getting ready for next month’s solar eclipse, which transects the continental United States on 21 August, and of course there are lots of maps.
Michael Zeiler, whose website about solar eclipse maps, coincidentally called Eclipse-Maps.com, I told you about in 2011, has launched a separate website dedicated to next month’s eclipse, called (wait for it) GreatAmericanEclipse.com. There are eclipse maps for every state the path passes through, various maps presenting additional information, and a 10-foot-long strip map of the path of totality.
But knowing an eclipse’s path isn’t always enough. There’s nothing worse than spending a fortune to get to an eclipse-viewing spot only to discover it’s clouded over. You can’t predict the skies far enough in advance, but you can factor in the likelihood that skies will be clear or cloudy for a given location, based on historical weather data. That’s what NOAA’s eclipse cloudiness maps do. [GeoLounge]
