"When will the Antarctic Ozone Hole recover?"

by

Dr. Paul A. Newman

Atmospheric Physicist,

Atmospheric Chemistry and Dynamics Branch

NASA's Goddard Space Flight Centre

Abstract:
The Antarctic ozone hole develops each year and culminates by early spring.  Antarctic   ozone values have been monitored since 1979 using satellite observations. Ozone is   mainly destroyed by halogen (chlorine and bromine) catalytic cycles. In this talk, Dr. Newman will show the relationships of halogen and temperature variations to both the size and depth of the hole and discuss the current assessments and future recovery of the ozone hole in light of international agreements that limit or phase out production of halogens.

Biography:
Dr. Newman is a Seattle native who graduated from Seattle University in 1978 with a B.Sc.   in Physics & a minor in mathematics. In 1984 he completed his PhD in physics at Iowa State University. From 1984 to 1986, Dr. Newman was a National Research Council fellow, worked for Applied Research Corporation from 1986 to 1989, and the Universities Space Research Associates from 1989 to 1990. He has been with NASA since 1990, where his   principal area of research is stratospheric dynamics and chemistry.
