Trajectory Modeling:
A Powerful Tool for Identifying Air Pollution Sources. Glenn Gehring (TAMS Technology Specialist II) has created an effective step-by-step guide on using the HYSPLIT program to generate a simple backward trajectory and integrate it into a GIS program. There is also a guide to downloading emission inventory data from EPA's AirData website and integrating the data into a GIS program.

Plugging-in data and examining pollution sources, prevailing wind direction, meteorological conditions, backward trajectories and dispersion plumes during poor air quality events can give a tribal air professional a solid understanding of area sources and pollutants impacting the reservation.
