Intercomparison of three long-range trajectory models applied to Arctic haze

Trajectory analysis has been successfully applied as an analysis tool for atmospheric transport problems on scales ranging from 100’s to 1000’s of kilometers. A modeled trajectory is an estimate of the transport pathway of an infinitesimally small air parcel. This pathway represents an estimate of the centerline of an advected air mass subject to dispersion in the horizontal and vertical directions. These estimates are based on raw or analyzed data which have spatial and temporal gaps of up to several hundred kilometers and 12 hours, respectively. Trajectories corresponding to individual transport events thus provide, at best, an approximate indication of the mean motion of an advected air parcel.
