摘要
准确掌握地球大气中的水汽分布,了解水汽变化趋势对天气现象、全球气侯变化、数值预报有重要的理论研究及实用价值.文章系统地论述了利用地基GPS方法观测大气中水汽含量的原理.论述了在地基GPS技术中观测站遥测大气中水汽含量的理论基础,建立了利用GPS观测数据计算大气层水汽含量的理论模型,导出了Tm的计算公式,最后用实例论证了地基GPS测雨的可行性.
To sound water vapor precisely in the troposphere is essential for weather phenomenon research,global climate change research and numerical weather forecast.Paper systemic dissertate the ground-based GPS technology.Dissertate the theory foundation of remote sensing atmospheric water vapor content with ground-based GPS,establish the theory model for computing atmospheric water vapor content,and deduce the Tm computing equation,approve the feasibility of using ground-based GPS detect precipitation rain fall with example at length.
