Ozone day 2012 – part 2

Hey,

today I read an interesting article from NASA's Earth Observatory website that I would like to share with you:

The article includes a nice animation of ozone

Ozone day 2012 – 25 years from the Montreal protocol

Did you know that...
September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer. This designation was made on December 19, 1994, in commemoration of the date, in 1987, on which nations signed the Montreal Protocol on Substances that Deplete the Ozone Layer.

Here's a little animation of this year's ozone:
