英文摘要	A differential absorption lidar (DIAL) for measurement of atmospheric nitrogen dioxide (NO2) concentration is developed based on atmospheric backscattered signals. Two Nd:YAG lasers are used to pump into two dye lasers to produce two wavelengths lambda on (448.1 nm) and lambda off (446.6 nm), respectively. The NO2 absorption cross section varies with the change of ambient temperature. The changes of NO2 absorption cross section and the influence of inversion concentration are analyzed. The results show that when the horizontal profile is measured with the absorption cross section at room temperature of 20 degrees C as the reference value, the relative error of 1% can be caused by the temperature change of 1 degrees C. In vertical profile measurement, on the ground below 3 km, every 100 m increase in altitude can bring a relative error of 0.6%. By correcting the absorption cross section affected by temperature, the relative error of the measured concentration is less than 5%.On this basis, the experimental observation of atmospheric NO2 concentration profiles was carried out, and errors induced by temperature change were corrected. The experimental results show that the system is stable and reliable, and the temperature correction algorithm is effective. (C) 2021 The Authors. Published by Elsevier Ltd.
