This report describes the design and operation of the 1980 Urban Field Studies conducted as part of the Northeast Corridor Regional Modeling Project (NECRMP). The NECRMP is a multiphase program involving EPA and State/local agencies in the development of the Regional Oxidant Model and its application to the Northeastern United States. The 1980 Urban Field Studies were conducted to provide the data base of air quality and meteorological measurements necessary for modeling the major Corridor cities: Washington, Baltimore, New York and Boston. (A data base for modeling Philadelphia was acquired in 1979.) The 1980 field studies included continuous surface measurements of ozone, nitrogen oxides, hydrocarbons, wind speed, wind direction, temperature, and solar radiation in the vicinity of these cities. In addition, special measurements of hydrocarbon species, aircraft monitoring flights, sodars, pilot balloon observations, and rawinsonde soundings were employed to obtain air quality and meteorological measurements aloft in the Corridor. Quality assurance procedures conducted as part of the data collection/reduction tasks are also described in the report. Lists of the designated NECRMP monitoring sites and the dates/times of species sample collection and of measurements aloft are provided in the appendices.
