Research Statement

Dr. Caulton’s research focuses on increasing our understanding of the CO2 and CH4 cycles through better estimates of emissions. Her research has utilized both aircraft and ground based mobile platforms to characterize methane emissions from unconventional natural gas in Pennsylvania and urban environments. She has also used aircraft eddy covariance to measure forest CO2uptake. An important aspect of this research is improving emissions estimates through uncertainty analysis and replication.

Research Areas

• Greenhouse gas emissions from fossil fuel and urban environments
• Aircraft flux measurements of greenhouse gas sources
• Carbon cycle measurements
