Abstract

Differential optical absorption spectroscopy has been applied in atmospheric ammonia monitoring. The absorption of gaseous ammonia in the UV region between 190 nm and 230 nm has been examined and compared with spectra of interfering species and atmospheric transmission. A wavelength region around 210 nm was utilized in measurements of atmosphric ammonia over a 265 m path in a rural area with a detection limit of 1 ig/m
