用 Ｌ６２５ ３５５ ｎｍ 和 ５３２ ｎｍ 双通道瑞利（Ｒａｙｌｅｉｇｈ）散射激光富达，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．
The atmospheric densities and temperature distributions in the altitude range from 30 to 43 km at Hefei (31.9 ° N / 117.17 ° E) were observed using L625 355 nm and 532 nm dual-channel Rayleigh scattering laser Fuda. These results show good agreement with the density and temperature of NOAA / NMC and NASA / HALOE sites. In general, the variation of atmospheric density obtained by LIDAR from the density of NOAA / NMC and NASA / HALOE in the range of 34-43 km is about 10%, the temperature difference is less than 2 K, and the temperature deviation slightly larger than 34 km.
