Gas exchange between the land surface and the atmosphere is becoming an increasingly important component in modelling the state and the future of the climate system for enhanced climate and weather prediction. Due to the vast inhomogeneity of the land surface and the different scale-dependent characteristics of atmospheric motions there exists a scale gap in addressing these processes in current measurement and modelling methods: No clear concept exists to bridge from the local scale where exchange processes happen close to and at the land surface, to the scales which are suitable to describe and model these transports in the atmospheric environment e.g. by eddy-covariance methods and common boundary layer models, respectively. This project will approach this problem by an integrated methodology combining a set of different local measurement techniques with boundary layer scale estimates ranging from traditional techniques up to modern remote sensing tools and a suite of modelling approaches encompassing the whole atmospheric boundary layer. A flux chamber concept especially adapted to closing the scale gap from the measurement aspect will be designed and applied.
