Data on the presence of peroxyacetyl nitrate (PAN) concentrations in the ambient air over New Jersey in 1978-1980 are presented. Samples from 5 m over the ground were monitored for PAN using a gas chromatograph and peaks were recorded on a chart. Data were also taken on the total oxidant content, temperature, humidity, and total incident solar radiation. The PAN readings were taken hourly with a resolution of 0.2 ppb, and a concentration range of 0-10.6 ppm was found from 9600 readings over the 20 mos of the sampling. The daily PAN maximum exceeded 2 ppb on 43 days, mostly in August and September. The O3/PAN abundance ratio increased with temperature. Stepwise multiple regressions were performed to identify the contributing factors to PAN formation. The O3 and NO2 daily averages were the most significant predictor variables, and solar radiation had a negative impact on the occurrence of PAN. 12 references.
