Stephen G. Warren is an American atmospheric scientist and professor emeritus at the University of Washington. He is renowned for his contributions to understanding solar and infrared radiation processes in snow, clouds, and sea ice, as well as his pioneering work on the Snowball Earth climate dynamics. Warren was elected as a Fellow of the American Geophysical Union (AGU) in 2016 and has received numerous accolades for his research in atmospheric sciences and glaciology.
Education
[edit]Warren earned his Ph.D. in Physical Chemistry from Harvard University in 1973.[1] His doctoral research focused on the interaction of radiation with atmospheric particles, which laid the foundation for his later work on snow and ice albedo.
Academic career
[edit]After completing his Ph.D., Warren joined the faculty at the University of Washington in 1977. He served as a professor in the Department of Atmospheric Sciences and participated in interdisciplinary programs such as the Quaternary Research Center and Astrobiology Program.[1] Warren retired as professor emeritus but continues to contribute to research through collaborations with former students and colleagues.[2]
Research contributions
[edit]Warren’s research spans atmospheric physics, glaciology, and climate science. His key contributions include:
- **Solar Radiation Processes**: Investigated how light-absorbing impurities in snow affect its albedo and contribute to climate feedbacks.[2]
- **Snowball Earth Theory**: Studied oceanic processes during global glaciations to understand Cryogenian climate dynamics.[2]
- **Cloud Climatology**: Developed global datasets on cloud cover and cloud type distributions over land and oceans.[1]
- **Ice Optical Properties**: Published widely cited papers on the optical constants of ice from ultraviolet to microwave wavelengths.[3]
Warren has led field campaigns in polar regions, including Antarctica and Greenland, to study snow reflectance properties and cloud interactions with surface ice.
Awards
[edit]Warren has received numerous honors for his contributions to atmospheric sciences:
- **AGU Fellow** (2016): Recognized for advancing Earth sciences through groundbreaking research.[4]
- **Jule G. Charney Award** (American Meteorological Society): For significant contributions to atmospheric science.[5]
