摘要
针对北斗卫星导航系统(BDS)反演的大气可降水量(PWV)值能否替代成熟的全球定位系统(GPS)反演的PWV值应用于全球导航卫星系统气象学的问题,该文选取位于全球不同区域的26个GNSS连续运行站,首先将BDS反演PWV值分别与GPS反演PWV值和探空站PWV值进行精度对比分析;进而探究热带雨林气候,温带海洋性气候,热带草原气候及热带季风气候4种气候类型BDS反演PWV值在年、季时间尺度上的精度,以及BDS反演的PWV值应用于不同气候的特点。结果表明,BDS反演PWV值的变化趋势能够很好地反映不同气候类型的特点,BDS与GPS反演的PWV值精度相近,可将BDS反演PWV值应用于不同气候类型的GNSS气象学。
Aiming at the problem of whether the Beidou navigation satellite system(BDS)retrievable precipitable water vapor(PWV)could replace the mature global positioning system(GPS)retrievable PWV value in global navigation satellite system meteorology,this paper selected 26 GNSS continuous operation stations located in different regions of the world.Compare and analyze the accuracy of the PWV value of BDS inversion with the PWV value of GPS and the sounding station PWV value;Then,explore the precision of the PWV value of BDS inversion on the annual and seasonal time scales for four climate types:tropical rain forest climate,temperate oceanic climate,savannah climate and tropical monsoon climate,and the feature PWV value of BDS inversion applied to different climates.The results showed that the change trend of the PWV value of BDS inversion could well reflect the characteristics of different climate types,and the PWV value of BDS inversion and GPS were similar in accuracy,the PWV value of BDS inversion could be applied to GNSS meteorology for different climate types.
