摘要利用日本气象研究所的拉曼激光雷达，在2000 - 2004年期间测量了水汽混合比的垂直分布廓线。将测量值与气象观测塔上的无线电探空仪、湿度计以及激光雷达站点附近的全球定位系统（GPS）天线获得的值进行了比较。当w ≥ 0.5 g kg−1时，激光雷达获得的w值平均比修正的Meisei RS 2 -91无线电探空仪获得的值低1.2%，比修正的Vaisala RS 80-A无线电探空仪获得的值高17%。当w < 0.5 g kg−1时，激光雷达数据比无线电探空仪数据高19%或33%。当w ≥ 0.5 g kg−1时，激光雷达获得的w垂直变化与Meisei RS-01 G无线电探空仪和Meteolabor Snow白色无线电探空仪获得的结果平均相差5%。当w < 0.5 g kg−1时，激光雷达数据比无线电探空仪数据低37%或39%。的时间变化，W…
Abstract The vertical distribution profiles of the water vapor mixing ratio (w) were measured by Raman lidar at the Meteorological Research Institute, Japan, during the period from 2000 to 2004. The measured values were compared with those obtained with radiosondes, hygrometers on a meteorological observation tower, and global positioning system (GPS) antennas near the lidar site. The values of w obtained with the lidar were lower than those obtained with the corrected Meisei RS2-91 radiosonde by 1.2% on average and higher than those obtained with the corrected Vaisala RS80-A radiosonde by 17% for w ≥ 0.5 g kg−1. The lidar data were higher than those radiosondes’ data by 19% or 33% for w < 0.5 g kg−1. The vertical variations of w obtained with the lidar differed from those obtained with the Meisei RS-01G radiosonde and Meteolabor Snow White radiosonde by 5% on average for w ≥ 0.5 g kg−1. The lidar data were lower than those radiosondes’ data by 37% or 39% for w < 0.5 g kg−1. The temporal variations of w o...
