Research Interests

My research is focused on various aspects of cloud remote sensing. Clouds are a major regulating component of the earth-atmosphere energy budget and are known to be a key source of uncertainty in climate processes. I use measurements made by satellite and aircraft instruments to better understand the radiative effects of clouds.

Specific research topics

• Retrieval of cloud thermodynamic phase from satellite data (ice, water, mixed phase).
• Investigations of cloud properties using high spectral resolution infrared radiances.
• Development and testing of improved cirrus single scattering property models for remote sensing applications.
• Finding ways to incorporate in situ cloud microphysical measurements with remote sensing models.
• Relating clouds in the real world to those in radiative transfer models and satellite products.
