基　　金：Supported by the National Basic Research Program of China (Grant No. G2000078400) 摘　　要：Based on the dual-wavelength lidar we have developed, the 24 h continuous ob- servation has been realized in its sodium channel by using Faraday atomic filter technology and other relevant technologies. This will facilitate the continuous ob- servation of the sodium layer and the relevant upper atmosphere over Wuhan. A result of about 50 h observation indicates that the daytime column density of so- dium layer over Wuhan is slightly increased compared to that during the nighttime, and the characteristics of the sporadic sodium layer occurring during the daytime are compared with that during the nighttime. 关键词：LIDAR 24 H CONTINUOUS OBSERVATION sodium layer FARADAY atomic filter
