Astronomy presentation: Ozone and Astronomy
featuring Dr. Elizabeth Griffin, Herzberg Institute of Astrophysics.
The amount of ozone in the Earth's stratosphere is of critical importance to all bio-systems and individual forms of life. Relatively little is being done to improve our knowledge of the pre-CFC concentrations.
Dr. Griffin will describe how astronomy can play a very important part.
