Project description

The CoMet 2.0 Tropics mission will succeed the missions CoMet and CoMet 2.0 Arctic. Here, we will target biomass burning areas, where quantifying emission changes is complicated since emissions are dispersed over large areas, with emission rates that vary significantly inter-annually. The campaign will take place in a spring-season in Brazil.

The current paucity of appropriate observational datasets presents a large obstacle to improve our understanding and ability to model global wetlands. It is therefore generally accepted that aircraft measurements, in combination with chemical transport models, will help to reduce the uncertainty of global wetland CH4 emission estimates. Such data sets on large spatial scales, to complement local measurements and data from an emerging fleet of GHG measuring satellites, are still rare. Here, they will be used for an inverse modelling approach using high resolution atmospheric models (e.g., WRF), in combination with wetland models for regional budgeting.
