A Meteorological Synopsis of Aerosol Contributions and Air Mass History in Beltsville, MD
Room 244 (New Orleans Convention Center )
Megan K. Payne, Howard University, Washington, DC; and E. Joseph and J. D. Fuentes

During the summers of 2010 and 2011 there was an aerosol study conducted at Howard University Beltsville Campus (HUBC) in Beltsville, Maryland located 12 miles north of Downtown Washington D.C., to define and characterize aerosol contributions in a rural/urban area. This region is unique for its heterogeneity and rural/suburban surroundings, yet still having direct influences from two large metro cities (Baltimore, MD and Washington D.C.). At this location there is a suite of different size distribution samplers, chemical composition instruments, gas analyzers, and cloud condensation nuclei counters to give a wide range of information not only about spectrum of aerosols sizes, but to obtain their individual compounds and hygroscopicity. An in depth meteorological analysis has been conducted to determine the air mass trajectories common in this region, as well as, to single out localized characteristics of aerosols due to meso/micro scale meteorology. It is important to look at local air quality at HUBC because of the proximity to large populations of people, localized traffic since HUBC is located between I-95 and the BW Parkway, and to look at the effects air quality has on climate vs. weather.
