Research interests
I am a NERC Independent Research Fellow focusing on using satellite data and chemical transport models to understand changes in atmospheric methane. The NERC Fellowship is a novel approach to quantifying the largest uncertainty in the methane budget, the hydroxyl radical (OH). “COSMIC: Constraining OH using Satellite data and Machine learning to Investigate CH4 trends” will combine Earth observation (EO) data, machine learning and chemical transport modelling to provide long-term spatially and temporally varying estimates of OH and other tropospheric species, such as methane, ozone and nitrogen dioxide. The project will then take advantage of the EO constrained OH dataset to further investigate trends in atmospheric methane.
