Metropolitan Tracer Experiment (METREX)


Roland R. Draxler


NOAA Technical Memorandum ERL ARL-140, October 1985


Abstract - Several perfluorocarbon gas tracers were released at regular intervals for 1 year just outside of the metropolitan Washington, DC area.  Continuous 8 h samples were collected at a central downtown site and two adjacent suburban locations.  Monthly air samples were collected at 93 sites throughout the region at urban, suburban, and rural locations.  Meteorological measurements were made on 5 towers instrumented for this experiment.  The collected data can be used to quantify the errors from various dispersion modeling techniques as well as study the influence of an urban area on the dispersion of pollutants.
