Combining multi-platform, multi-tracer measurements with atmospheric modelling to better estimate fluxes of atmospheric constituents.

The global carbon cycle and the greenhouse gases carbon dioxide and methane are important drivers of climate change. Understanding the fluxes of these gases to and from the atmosphere is crucial for understanding past, present and future climate variability. This project focuses on using simultaneous co-located measurements of greenhouse gas amounts, together with modelling their atmospheric co-variability, to better estimate these fluxes by individual processes and on better temporal and spatial scales. In particular, co-located solar remote-sensing and in situ measurements will be combined, and the ability of the remote-sensing and in situ instruments to measure numerous gases will be exploited to improve flux estimates and atmospheric modelling.
