Trajectory model for tracing air transport phenomena

Trajectory models are important tools for studying transport phenomena in the atmosphere. In the environmental sciences, they are often used to establish source-receptor relationships of air pollutants. FLEXTRA can be used to calculate different types of forward or backward trajectories, and has facilities to estimate the uncertainty of trajectories. It is specifically designed to compute long time sequences of trajectories for many receptor locations. FLEXTRA may be used with the Metview meteorological workstation to visualize trajectories.
