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 remote, as opposed to in situ, measurements made by satellite and aircraft instruments to better understand the radiative effects of clouds.Specific research topics
- Detection of thin cirrus overlaying lower level water clouds in MODIS data.
- 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.
- Retrieval of cloud thermodynamic phase from satellite data (ice, water, mixed phase).
