There is a High School group out of Bishop, CA, named Earth to Sky Calculus. They release weather balloons regularly to study science. Their funding comes from donations to buy the helium.
Details of their experiments, pictures, etc appear regularly on http://spaceweather.com/ There is a picture from their Sept. 6 launch which was taken of the “Rough Fire” in Ca.

A group of fairly brilliant high school students who send weather balloons to the stratosphere for both research and profit.
