| 摘 要： | 利用武汉大学Rayleieh/钠荧光散射激光雷达和无线电探空仪进行联合探测的数据,反演出武汉地区上空(30.5°N,114.4°W)0—65km处的密度和温度分布曲线,并简单阐述了激光雷达的工作原理。将测量结果和MSISE-90参考大气模式比较,二者结果基本符合,温度廓线在中层顶附近和模式的差别约为3K。同时利用激光雷达探测到了中层大气中的重力波活动。

| Abstract: | Vertical distributions of atmosphereic density and temperature over Wuhan (30.5N, 114.4E) from ground to 65km have been obtained by Rayleigh Scattering Lidar with high temporal and special resolution and radiosondes. A method to derive the density and temperature from the photon counts collected by lidar is described briefly. The density and temperature profiles agree very well with MSISE-90 atmosphere model and the temperature difference between the derived profiles and model were less than 3 K near the stratospause. The errors involved in the derived values are presented and analyzed. Preliminary analysis of temperature variations in a night revealed fluctuations with characteristics resembling those large-scale gravity waves. |
