Description:
Data is presented for gaseous ammonia and nitric acid and particulate ammonium ion and nitrate ion concentrations in air samples collected in support of the PEPE-NEROS study during the summer of 1980. Ground-level samples were collected near Croton, Ohio; aerial samples were also taken from an aircraft during several flights. Sampling and analyses were accomplished using the hollow and packed tube tungstic acid method that permits short sampling times of 10-30 minutes. Feasibility of sampling from aircraft was established. Quality control was maintained by measuring the preconcentration tube efficiency before and during field analysis.
