| 摘 要： | 水汽是大气成分中重要的组成部分，了解全球水汽分布规律及其形成机制对于未来全球气候至关重要。并且，GPS无线电掩星技术用于GPS气象学，为研究者提供了高精度、全球性、连续性的数据资料，特别是海洋及无人区的数据。本研究主要利用GPS无线电掩星数据反演全球水汽所对应的绝对湿度值，从而得到较为精确和全面的全球水汽分布情况，为进一步提升气象预报、未来气候分析的准确性及未来的大气研究提供精确的参考数据。

| Abstract: | Water vapor is an important part in the Earth＇ s at- mosphere, thus it is ve~7 important for the study of global cli- mate in the future to understand the atmospheric composition, distribution and formation mechanism of global water vapor. What＇ s more, the GPS radio occultation technique used in the GPS meteorology can provide data with high accuracy, world- wide range and hing continuity for the researchers, espeeially the data in the ocean and unmanned area . This research main- ly uses the absolute humidity of the corresponding global water vapor inversion of GPS radio occultation data value, so as to ob- tain more accurate and comprehensive global water vapor distri- bution situation and provide more accurate reference data for enhancing the accuracy of weather forecasting and climate anal- ysis in the future research. |
