摘要：

A multiwavelength method to improve the accuracy of a differential absorption lidar (DIAL) for measuring SO2 in the lower atmosphere is presented. A dual-DIAL method consisting of a combination of two DIAL pairs (three or four measurement wavelengths) is proposed, and the measurement error is estimated from the lidar equation. By the selection of appropriate measurement wavelengths, the effects of ozone and aerosols can be suppressed. In principle, the accuracy can be improved to below 1 ppb for 300-m range resolution.
