ERAQS
Program Title: Eastern Regional Air Quality Study The Eastern Regional Air Quality study (ERAQS) extended the comprehensive aerometric measurements initiated under the Sulfate Regional Experiment (SURE). This was done with two major objectives in mind: 1) To complete two years of continuous air quality data acquisition in the northeastern United States in order to check seasonal and annual variability of air pollutants and precursor materials and extend the SURE data base. 2) To provide one full year of collocated aerometric and precipitation chemistry data in the northeastern United States in order to define any association between local air quality data and acidic deposition. The nine Class I SURE stations were operated continuously for an additional period of 14 months according to the protocols developed for the SURE. Simultaneously, collocated precipitation chemistry samples were collected on a daily (event) basis. See: "http://src.com/~epriasdc/eraqs/eraqs.htm" for information on the ERAQS study.
