Today, the MAMM team have had a new paper published based on one of our flights in July 2012. It’s quite exciting, as published papers are the end result of all our hard work, and the main way that others can find out about what we’ve been studying.

The paper is about emissions of methane and carbon dioxide from wetlands in Finland and Sweden, which is no surprise if you followed our field work! We used measurements of methane, carbon dioxide and the meteorology from the aircraft to work out how much of these greenhouse gases was coming off from the wetlands to explain the pattern we saw in the measurements.

This technique for working out the methane and carbon dioxide emissions compared really well with other methods we have of working this out from measurements on the ground or on towers just above the ground. This gives us confidence that the methods we have used are sound and the emissions we have worked out are good estimates.

We compared these emissions estimates with some computer simulations, and it turned out that our emissions were much larger than what the models simulated. This kind of comparison is a good starting point to try and improve the models and to make them more realistic, which is what we want if we are to use the models to try and test how much methane will be released under different conditions.
