Nitrate radical (NO3) is a significant nocturnal trace gas in the atmosphere, its oxidative capacity in the night is comparable with that of diurnal OH radical. NO3 radical contributes to the oxidation of hydrocarbons and organic sulfur species, as well as the conversion of nitrogen oxides to nitric acid at night. Accurate measurement of its concentration in the atmosphere has become an essential topic in current research. NO3 radical has the short lifetime and low concentration,which brings a challenge to detect NO3 radical. In this paper, three detection methods of Differential optical absorption spectroscopy (DOAS) cavity ring-down spectroscopy (CRDS) and cavity enhanced absorption
