Transportmodell FLEXPART


The Lagrangian particle dispersion model FLEXPART is run on ECMWF data to explore the transport and dispersion of various atmospheric constituents, from greenhouse gases, radionuclides and aerosols like black carbon to volcanic ash released during eruptions. The model is used with various inversion techniques to infer emission estimates of many atmospheric compounds. This helps improving transport simulations of these substances and to understand their impacts on air quality and effects on the climate system. The model can also be used to develop Lagrangian climatologies of energy or water transport in the atmosphere.


Transport in the Atmosphere

The FLEXPART model, based on ECMWF data, will be used to analyse total energy, heat and water transport in the atmosphere. By performing domain-filling transport model simulations with the Lagrangian particle dispersion model, as well as forward and backward simulations for particular sites, Lagrangian transport climatologies, as well as global statistics, can be established. Furthermore, case studies of particular extreme events shall be performed, for example heat waves and extreme precipitation events. The main goal is to gain a better understanding of the physical processes in the atmosphere. With this method the heat transport during heat waves, or the global moisture transport in the atmosphere (Stohl and James, 2004) can be analysed.
