Ozone detection using visible light and a custom ...

07/08/2012· We used two methods of ozone detection in this experiment. The first method uses a MQ-131 gas sensor which responds to the presence of ozone by changing the resistance within the device. This allowed us to construct a circuit with this ozone detector where we measured voltage to observe the change in ozone concentration. Our second method of ozone detection utilized ozone's absorption …

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 …
