【摘要】 基于福建省闽南地区6个GPS/MET站点的观测资料,利用从IGS下载的精密星历数据,通过GAMIT软件计算出对流层湿延迟(Zenith Wet Delay,ZWD);利用厦门2016年的实际气象资料统计拟合出加权平均温度模型,得到加权平均温度,从而反演出大气可降水量(PWV),并与由探空资料反演的PWV相比较,由GAMIT软件系统反演出大气可降水量结果能够达到实际业务需求的精度。更多还原

【Abstract】 Based on the observation data from Six GPS/MET Stations in South Fujian Province and the precise ephemeris data downloaded from the IGS,this paper introduced the GAMIT software and the data inverting process to calculate the wet tropospheric delay(Zenith Wet Delay,ZWD). The weighted average temperature model was fitted by using the actual meteorological data of Xiamen in 2016 to obtain weighted average temperature,and then the results of atmospheric precipitable water vapor(PWV)was inverted. By comparing with PWV inverted from sounding data,the results showed that the inversion by GAMIT software could achieve the requested accuracy of atmospheric precipitable water vapor.更多还原
