Review of NMOC, NOx and NMOC/NOx ratios measured in 1984 and 1985
During the summers of 1984 and 1985, morning (6-9AM) measurements of ambient nonmethane organic compounds (NMOC) were collected at 22 and 19 urban sites, respectively. The data were collected by State and local agencies which contributed grant funds and personnel. The Environmental Protection Agency (EPA) managed the analysis and provided NMOC sampling equipment. The method of determining NMOC levels was the cryogenic preconcentration direct flame-ionization detection (PDFID) described by McElroy. Data were collected to provide input values for the Empirical Kinetic Modeling Approach (EKMA), a computer program which estimates hydrocarbon control requirements necessary to attain the National Ambient Air Quality Standard (NAAQS) for ozone. One of the key inputs to EKMA is the Nonmethane Organic Compound/Nitrogen Oxides (NMOC/NOx) ratio. Thus, a collocated NOx instrument was operated at each NMOC site.
