基于 SDCORS 的区域可降水汽含量分析

摘要

SDCORS data are processed to estimate the precipitation water vapor (PWV) over Shandong with the time resolution of one hour by the GAMIT/GLOBK .The GPS/PWV series are compared with the NCEP reanalysis data and local precipitation to verify the GPS/PWV accuracy and reliability .The results showed that the GPS/PWV from the SD‐CORS data can be used in the meteorological research and as oneindicator of short‐term pre‐diction of precipitation and weather monitoring .%利用GAMIT／GLOBK软件对SDCORS站的观测数据进行解算，获得了山东地区各测站的时间间隔为1小时的大气可降水汽序列，将其与NCEP模型插值计算得到的可降水汽含量、地面站点的实际降水量进行了比较分析。结果表明：利用SDCORS观测数据所反演的可降水汽含量有一定的使用价值，可以用于气象学上大气可降水汽含量的研究；G PS可降水汽含量能够作为降水短期预报的指标，能够监测天气变化的过程。
