The composition of the atmosphere is affected by human activities:  fossil fuel use, industry, agricultural practices, wood burning, deforestation, changes in land use, etc.  My research group used global models and analyses of atmospheric data to improve our understanding of the processes affecting atmospheric composition and climate, and the changes wrought by human activity. Much of our recent work involved evaluating transport in models using data from the Aura satellite.

At Harvard I continue to collaborate with Loretta Mickley on climate related research. I have also been involved with the development of the GEOS-Chem model.

I am part of the TES Science Team, and I am analyzing the TES data for tropospheric ozone and CO. I also analyze MLS data for ozone and CO in the upper troposphere and lower stratosphere. I am using the satellite data to evaluate transport in the GEOS-4, GEOS-5, and MERRA assimilated meteorological fields that drive the GEOS-Chem and GMI models.

Other current research interests include hindcasts of atmospheric composition since 1990; analysis of trends and interannual variability in tropospheric ozone, particularly over Europe; predicting fires in North America using an ensemble of climate models, and the effects of these fires on air quality in the 2050s. Other recent work has focused on the effects of boreal fires on atmospheric composition, and analysis of MISR data for injection heights of fire plumes. More details can be found on my research page, and broader activities using the GEOS-Chem model can be found here.
