Acid Rain & Ozone Hole Pioneer Dies at 87

Atmospheric chemist Stuart Penkett, who passed away at 87, was instrumental in understanding and mitigating significant environmental threats. His early work in the 1970s identified the chemical processes responsible for acid rain, a discovery that transformed pollution control efforts.

Later, in the 1980s, Penkett's research at the University of East Anglia elucidated the mechanisms behind ozone layer depletion. His measurements pinpointed chlorofluorocarbons and other substances as key culprits, significantly contributing to the landmark 1987 Montreal Protocol.

Penkett also established the Weybourne Atmospheric Observatory, a key monitoring station, and advanced airborne atmospheric research capabilities. His contributions were recognized with numerous awards, solidifying his legacy as a pivotal figure in atmospheric science.
