NASA - Discovering the Ozone Hole: Q&A With Pawan Bhartia

Ozone was a hot topic among scientists an August 1985 meeting in Salzburg, Austria, a few days after Pawan Bhartia presented the first satellite image of the ozone hole. In attendance were Donald Heath, who initiated the ozone measurement program at Goddard in the late 1960s, and the late Sherry Rowland, who later received the Noble Prize for ozone layer research.
