| 摘 要： | 地基GPS技术已被公认为观测大气水汽的最具潜力手段，而天顶湿延迟（ZWD）是地基GPS解算高精度水汽的关键量。瑞士伯尔尼大学天文研究所开发的BERNESE软件在解算天顶湿延迟方面独树一帜。以香港地基GPS连续运行参考站数据为解算实例，详细介绍了BERNESE软件解算ZWD的基本步骤和相关设置，并对有气象观测文件、数据跨天、跨周和定点解算ZWD情况的特殊设置进行了研究，结果表明BERNESE软件完全胜任ZWD解算工作。 |

| Abstract: | Ground-based GPS technology has recognized as a tool to observe the atmosphere water vapor with the highest potential.The zenith wet delay(ZWD) is the key factor to obtain water vapor with high precision.The BERNESE software developed by the Astronomical Institute,University of Bern is one of most distinguishing means for calculating ZWD.The basic steps and relevant settings using the BERNESE software to calculate ZWD are introduced on the basis of the data from the continuously operating reference stations over Hongkong,and some special cases are studied,such as having meteorological observation files and calculating ZWD continuously for adjacent days and weeks,or calculating ZWD at some specific time points.The results indicate that the BERNESE software can be used to calculate ZWD perfectly. |
