| 摘 要： | 基于香港CORS站的实测GPS和气象数据，设计并实现利用多历元观测值层析水汽的方法，分析不同天气对该方法层析结果的影响。结果表明，该方法在RMS和误差统计方面均优于传统方法。此外，不同天气对层析结果影响不同，但无论在何种天气下，该方法均优于传统方法。

| Abstract: | We propose a tomographic approach using multi-epoch observations based on GPS data from Hong Kong CORS, and analyze the influences under different weather conditions. The results show that the RMS and error statistics of our proposed approach are better than the traditional method. In addition, tomographic results vary according to weather conditions. However, whatever weather conditions prevail, the proposed approach is superior than the traditional method. |
