基于区域 CORS 的可降水汽含量反演及其精度分析
Retrieval and Accuracy Analysis of the Precipitable Water Vapor Content Based on the Regional CORS
摘要
Abstract
To test the accuracy of precipitable water vapor (PWV ) content determined by regional CORS ,the data of SDCORS in 2012 are used to estimate PWV over Shandong in this paper .Error equations are solved with the multi parameter method to calculate the trop‐osphere delay from which the precipitable water vapor content is determined .The method of evaluating the accuracy of the precipitable water vapor content by the positioning accuracy is put forward .Also the CORS‐derived PWV is comparing with NCEP/PWV .The results in‐dicates that PWV derived with the regional CORS data can be of high precision .关键词
