Detailed Description

Each particle's track consists of events reported as the particle is advected through the model domain. Events are snapshots of particle state, along with optional metadata, at a particular moment in time.

Particles have no ID property. A particle can be uniquely identified by the unique combination of its release attributes (model, package, position, and time). This is possible because only one particle may be released from a given point at a given time.

This module consumes particle events and is responsible for writing them to one or more track files, binary or CSV, and for logging the events if requested. Each track file is associated with either a PRP package or with the full PRT model (there may only be 1 such latter).
