Paper Abstract

12 This paper reports the results of ammonia measurements near two CAFOs. In September of 1999, measurements were conducted for 48 hours downwind of a large-scale CAFO using two open- path monitors; an ultra violet differential optical absorption spectrometer (UV DOAS), and a Fourier transform interferometer (FTIR). In March of 2000, measurements were conducted at a much smaller CAFO using UV DOAS. This paper describes the calibration of a UV DOAS, compares UV DOAS and FTIR measurements, describes the effects of wind and atmospheric stability on ambient ammonia concentration, and suggests potential applications for open-path monitors for assessing public health risk.
