Backtrajectory analysis uses interpolated measured or modeled meteorological fields to estimate the most likely central path over geographical areas that provided air to a receptor at a given time.  The method essentially follows a parcel of air backward for a specified length of time.  Backtrajectories are an oversimplification of the atmosphere in that dispersion is not accounted for.

A commonly used trajectory model is the Hybrid-Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model developed by the NOAA Air Resources Laboratory (ARL). The product presented here is a 60-hour HYSPLIT back trajectory ending at 12 UTC at different heights over the site.  It is based upon the most recent NCEP Global Forecast System (GFS) model run.
