Trajectory Models

Trajectory models are very helpful tools for the investigation of atmospheric transport processes. For instance, they can be used for identifying source regions of air pollutants or to estimate the dispersion of particles or sound rays. There are numerous models for the computing of trajectories. Some of it can be used here for individual purposes.


FLEXTRA - Air mass trajectories

FLEXPART - Particle dispersion

HYSPLIT - Air mass trajectories

HARPA - Sound ray trajectories
