I have participated in several research projects studying upper tropospheric water vapor.

Above the boundary layer, in the upper troposphere, water vapor is critical to regulating climate through the water vapor feedback. I have used in situ and remotely sensed observations to study upper tropospheric water vapor and have examined its representation in global models. I am particularly interested in the mechanisms that transport water vapor in the tropics and how these mechanisms relate to climate change.

Recent work in this area concerns the transport of moisture into the subtropics using satellite data, conventional meteorological data, and atmospheric model results.

 At the Climate and Radiation Branch at the Goddard Space Flight Center, I used TOVS radiance observations to examine the moisture distribution in general circulation models.

While in the Geology and Geophysics Department at Yale University, I examined the accuracy of satellite observations, in situ moisure measurements, and radiative transfer calculations using simulaneous aircraft and GOES satellite observations.
