Our research group studies fundamental physical processes that govern terrestrial climate change, with emphasis on observations and particular attention to the Earth’s polar regions.
Our work is supported by the US National Science Foundation, the US Department of Energy, and NASA. Ongoing research activities include:

  • The ARM West Antarctic Radiation Experiment (AWARE)  [DOE link]
  • Atmospheric spectroscopy and spectroradiometry for cloud physics and cloud-aerosol interactions
  •  Satellite remote sensing of the Antarctic atmosphere and energy balance at the ice sheet surface
  • Satellite remote sensing of Earth’s polar regions
  • Field and aircraft measurements of atmosphere-ice interaction in the high Arctic
  • Application of global climate model simulation to the polar regions
  • New instrumentation and techniques for space-based remote sensing
  • Activity of solar-type stars as analogs of climate-related solar variability
  • Stellar astrophysics related to solar variability and climate
