摘要
对流层的变化与人类活动息息相关。随着全球卫星导航系统在对流层水汽监测中应用的探索,人们对两者的结合提出了更高要求。利用JSCORS观测数据求取大气可降水量并利用权威数据进行验证,同时利用无线电探空反演成果与之对比,证明了方案的正确性。最后利用该方案成功建立了南京区域数值天气预报模型,为今后相关研究提供一定参考。
Changes in troposphere are closely related with human activities.With the development of GPS technology and its gradually application in troposphere water vapor retrieving,higher requirements are proposed to combine these two technologies to obtain higher precise results.Aims of this study were to present a new scheme to get the atmospheric precipitation value using JSCORS observation data.The results were validated using an authoritative datum.Meanwhile,the inversion outcomes of radiosonde were utilized to verify the correction of the proposed scheme.Based on the scheme,a numerical weather forecast model of Nanjing area was established,which would provide better references for relevant research in the future.
