Since some air pollutant concentrations are known to vary systematically with latitude, mountain sites were located at several laltitudes, reflecting different transport distances and times from major air pollution source regions. MCCP's specific locations are: Mt. Mitchell, NC; Whitetop Mt., VA; Shenandoah National Park, VA; Whiteface Mt, NY; Mt. Moosilauke, NH; and Howland Forest, ME. The sites were established during the late 1985-early 1986 time frame and alle are currently functioning. Three of the sites are operating monitoring stations at several elevations. The Atmospheric Environment Service of Canada is collaborating with the United States EPA in this project by operating similar sites at Mt. Tremblant and Roundtop Mountain in Quebec Province. Experimental design at the MCCP includes the selection of sites, establishment of protocols, coordidnation, data base oversight, and preparation of interpretive reports. The MCCP is designed to define the concentration of selected acidic compounds and associated oxidants in the gaseous and liquid phases for above-cloud base forests.
