The NOAA Air Resources Laboratory Field Research Division (ARLFRD) participated in an atmospheric
tracer field study in Midtown Manhattan, NY during August 2005. The study is the second of three experiments
under New York City’s Urban Dispersion Program (UDP) and has since become known as MID05. UDP was
designed to research and predict how chemical and biological pollutants would transport and disperse
throughout a large city environment. UDP will expand on the knowledge gained from similar tracer studies
conducted in smaller urban cities such as in Oklahoma City (Joint Urban 2003) and Salt Lake City (Urban 2000).
The study is designed to study four areas of airborne transport. They are:
