FLEXTRA is an atmospheric trajectory model used by a large user community. It can be driven by meteorological input data from a variety of global and regional models including ECMWF analyses and forecasts. FLEXTRA can compute both forward and background backward trajectories using various trajectory types such as: three-dimensional, model level, mixing layer, isobaric and isentropic trajectories.
