A leading NASA researcher on ozone depletion and air pollution, credited with improving local pollution measurement tools and many other advances in climate science, has died at age 80.
Stanley Sander became known for his research on atmospheric chemistry at the Jet Propulsion Laboratory, where he began his career in 1971.
“Stan had a profound impact on our understanding of stratospheric ozone depletion, tropospheric air pollution, and climate-related greenhouse gases,” NASA said in a statement announcing his death.
Sander's research in laboratory measurements has been used to help other scientists reach consensus on a variety of environmental issues, including developing tools for monitoring air quality and shaping environmental policy.
He also conducted studies of the chemistry of methane on Mars, halogen gases on Venus, and hydrocarbons in the atmosphere of Titan.
“Stan’s scientific accomplishments have been monumental,” NASA said in a statement. “He has authored more than 180 peer-reviewed publications, beginning with his 1976 work on the oxidation of sulfur dioxide. His research covers key aspects of atmospheric chemistry, from chlorine and bromine to nitrogen oxides, sulfur compounds, and peroxides.”
NASA noted that Sander's influence extended beyond the hard sciences to mentoring young scientists. He guided 40 postdoctoral fellows and more than two dozen graduate and undergraduate students in their quest to understand atmospheric chemistry.
“Those of us who were fortunate to learn under Stan's guidance will remember his kindness and resilience during difficult times,” the press release said.
Sander has received numerous awards for his outstanding achievements, including two NASA Exceptional Achievement Medals and the NASA Exceptional Service Medal.
