Random Walk Models for the Footprint Problem in the Turbulent Atmosphere

INTAS (EC INTAS-99-1501)

From 03/2000 to 03/2003

Principal Investigator: Thomas Foken
Staff: Mathias Göckede

This project is aimed to the development of new computational stochastic models and measurement technique for simulating and evaluating the transport of gases and aerosol particles in the turbulent atmosphere with specific applications to the footprint problem which assumes to evaluate the concentration and its fluxes at the detector contributed from different surface and volume sources. The main investigation instruments are the stochastic differential equations which result, after an appropriate approximation, in random walk algorithms for simulating direct and backward Lagrangian trajectories of the parcels of the gas flow and aerosol particles. The results from modelling are verified and applied for ongoing field measurements of concentrations and fluxes of gases and aerosol particles.
