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.
