| 摘 要： | 为达到高度计几厘米测高精度,湿对流层校正范围为3~45 cm,精确计算湿对流层校正是至关重要的。本文利用美国国家环境预报中心(National Centers for Environmental Prediction,NCEP)数据,采用模型法计算高度计湿对流层校正。计算结果与无线电探空仪计算结果比较,偏差为0.01 cm,均方根为2 cm;与Jason-1模型法湿对流层校正产品比较,偏差为0.2 cm,均方根为1.4 cm。因此,利用NCEP数据计算高度计湿对流层校正精度较高,能够满足高度计大气湿对流层校正精度要求。为高度计大气湿对流层校正的计算提供1种新方法。

| Abstract: | In order to achieve the accuracy of a few centimeters for altimeter range measurement,model wet troposphere range correction which is of 3~45 cm must be accurately calculated.In this paper,wet troposphere range corrections are calculated using the model method based on National Centers for Environmental Prediction(NCEP) data.Comparing with Jason-1 wet correction product,the mean variation is 0.2 cm and RMS error is 1.4 cm.Comparing with correction calculated using radiosonde data,the mean variation is 0.01 ... |
