【摘要】 用1.35厘米波长地面微波辐射计进行了全年四个季节的观测.采用蒙特卡洛法对资料进行了反演.七十多份资料的统计结果表明:水汽总量的相对误差为5.3％,低层水汽廓线(750毫巴以下)的相对误差在20％以下,对水汽总量及廓线随时间的演变与天气背景的关系亦作了初步分析.更多还原

【Abstract】 In four seasons of 1982 measurements of atmospheric water vapor profiles and total precipitable water were made by a ground-based microwave radiometer operating at 1.35 cm wavelength. All data were processed by using Monte Carlo Method. The statistical results of more than seventy cases show that the relative error compared to the radiosonde observations is 5.3% for the total precipitable water vapor and less than 20% for humidity profiles in the lower atmosphere below 750mb. In addition, the relationship between the weather background and both the humidity profiles and the total precipitable water vapor were analyzed.更多还原
