We study the coupled interactions across biogenic/anthropogenic emissions, atmospheric chemistry, and the broader climate. Example works are diagnosing the temperature and hydrological dependence of methane emissions, evaluating the sensitivity of the global methane budget to atmospheric oxidation, and evaluating the relationship between rainfall and NO2 emissions.
Methane is a crucial greenhouse gas whose emission reduction can effectively mitigate climate change on a decadal time scale. Our study explores methane emission characteristics from point sources to global scale. We further combine isotopic measurements with satellite data to improve emission quantification.
As the volume of new observations explodes, advancing the state of inverse methodology is crucial for full exploitation of these data. Our work evaluates the impact of model transport error for the accuracy of methane source inversions and develop new inversion formalisms for improved identifications of missing greenhouse gas sources from space.
