Wetland areas are substantial emitters of methane, a major greenhouse gas. There is a large uncertainty in these emissions and crucially, how they may respond to a warming climate. We are developing a Tropical Wetland Digital Twin, combining models, observations and machine-learning, in order to better understand when and where methane is being emitted and how such emissions may change in the future. Our Digital Twin will not only improve our understanding of these emissions but vitally, will get this information into the hands of decision-makers and impact upon policy.
