| 摘 要： | 用L625 355
nm和532 nm双通道瑞利(Rayleigh)散射激光雷达,分别观测合肥(31.9°N/117.17°E)地区30～43
km高度范围内的大气密度和温度分布.这些结果与NOAA/NMC和NASA/HALOE相邻地点的密度和温度表现了较好的一致性.一般情况下,在34～43
km高度范围内激光雷达获得的大气密度与NOAA/NMC和NASA/HALOE密度的偏差大约为10%,温度差别小于2
K,而34 km以下温度偏差稍大.

| Abstract: | L625 Rayleigh scattering lidar made the measurements of air density and temperature over the altitudes of 30-43 km at Hefei (31.9'N/117.17'E), two laser beams with 355 nm and 532 nm were employed, respectively. The results of lidar agreed well with ones of NOAA/NMC and NASA/HALOE. Generally, the differences of density.were about 10%, and temperature biases were less than 2 K between the altitude 34 km and 43 km, but a little larger below 34 km. |
