摘　　要：利用CE-318型太阳光度计936 nm波段的太阳辐射观测资料,采用改进的Langley法反演了郑州地区大气柱水汽含量,并分析了大气柱水汽含量与地面水汽压之间的关系。结果表明:郑州地区大气柱水汽含量的季节变化:夏季>秋季>春季>冬季,日变化为早晚低,中午高;郑州地区大气柱水汽含量与地面水汽压之间存在着良好的线性关系。Based on the solar radiation observations from CE-318 sun-photometer at the 936 nm channel,the improved Langley technique is used to retrieve the atmospheric column water vapor content over Zhengzhou.The empirical expression of the relation between atmospheric column water vapor content and ground water vapor pressure is derived.The calculating results show that the seasonal variation of the atmospheric column water vapor content was the greatest in summer,the second in autumn,and the least in winter.The diurnal evolution shows that there is a lower value in morning and evening,and higher value appear around noon.There is a good linear relationship between atmospheric column water vapor content and ground water vapor pressure.
