Art Rangno has posted a pdf of the 10th edition his popular Guide to the Sky Poster for mass consumption. Printed copies of these beautiful posters, published between 1987 and 2005 are no longer available so this is your chance to enjoy Art's beautiful photographs of clouds and his clear, succinct, and poetic descriptions of the clouds, how they form, and what they mean weatherwise.

Art is a meteorologist formerly in airborne cloud studies at the University of Washington and now lives in Arizona where he has an unobstructed view of the western sky and posts fabulous photographs of the clouds, meteorological news, and fun facts for skywatchers on his website Cloud-Maven.com

It was Art's poster, taped to a closet door, that sparked my interest in clouds in 2008. And, because there are so darn many of them, it has taken me longer than I had planned to write my book about them. I am making progress. Stay tuned!
