Error analysis for NO2 DIAL measurement in the troposphere

NO2 concentration profiles, which are important in studies of atmospheric chemistry and urban pollution, were measured by a differential absorption lidar (DIAL) based on a pair of Nd:YAG pumped dye lasers. In the experiments, 448.1 nm and 446.8 nm were used for “on” and “off” wavelengths, respectively. NO2 concentration profiles of 0–40 ppb were obtained for altitudes between 900 and 2250 m with a 150 m range resolution. Null error, which was estimated by deviation of the null profile from zero, was <2 ppb. The statistical error, systematic error from aerosols, and error due to uncertainty of absorption cross section were <3.35 ppb, <4.44 ppb and <1 ppb, respectively. The total error was about 6.0 ppb. The estimation of aerosol backscatter and extinction error in NO2 measurement due to inhomogeneous aerosol distribution is treated in detail.
