Research Interests
My research interest is primarily in satellite remote sensing of clouds and its application to climate study.
Deep convective clouds play a major role in the Earth's climate by transporting heat, moisture, and momentum from the lower to the upper troposphere. Those penetrating into the tropical tropopause layer (TTL) also contribute to the exchange of air between the troposphere and the stratosphere. My research in the past few years focused on deriving properties of tropical deep convective clouds using the passive microwave measurements acquired by the AMSU-B aboard NOAA satellites and the measurements from the PR and VIRS aboard TRMM satellite. I have developed an algorithm to detect tropical deep convective clouds using the three water vapor channels around 183.3 GHz from the AMSU-B. This algorithm has been used to derive the diurnal cycle of tropical deep convective clouds, which is shifted a few hours earlier than that detected from infrared measurements.
My current research focuses on the investigation of the spatial and temporal distributions of cirrus clouds over the tropics and their radiative forcing on the basis of the MODIS, CERES, and AIRS data. Additionally, I am working on developing new algorithms to retrieve the optical and microphysical/macrophysical properties of ice clouds.
