Measurement error for NO2 profiling in the lower troposphere, including the effects of aerosol backscatter, molecular backscatter, and extinction due to inhomogeneous aerosol distribution, is estimated for vertical NO2 concentration profiles measured by differential absorption lidar (DIAL). Vertical NO2 concentration profiles of 0 to 40 ppb and null profiles are obtained for an altitude of 900 to 2250 m with a 150-m range resolution. The deviation of the null profiles from zero, which provides a measure of how precisely the laser beams were aligned, was <2.0 ppb. The mean statistical error, systematic error from aerosol, and absorption cross section error were 3.4, <3.0, and <1.2 ppb, respectively.
