The composite trajectory service consists of services for WCS data access, single trajectory calculation and trajectory aggregation. The wind data are to be both provided by servers that can deliver 4D model wind data (u,v,w,t).

The single trajectory service uses the 4D input winds for a specific region and time and calculates forward or backward trajectories. The same algorithm is used for the forecast and historical 4D trajectories.

The trajectory aggregator is a compound service that can aggregate multiple trajectories using a variety of algorithms.

With these services it is possible to build a variety of air quality analysis applications such as the Combined Aerosol Trajectory Tool, CATT.
