摘要: 气象作为最早应用BDS的重要领域之一,现已逐渐形成北斗全面应用的新格局。利用基于BDS的地基增强系统开展气象行业系统建设与应用,一方面可以有效提高我国卫星导航系统气象观测能力,另一方面也可以降低目前卫星导航系统气象应用对GPS和GLONASS的依赖,无论是对于我国气象事业的发展还是对北斗产业化的支撑都具有重要意义。本文调研了目前卫星导航数值天气模式应用进展,并基于BDS开展数值天气模式应用,对实时反演的大气可降水量(PWV)进行观测误差估计,通过区域数值天气模式BDS-PWV同化应用试验,初步评估了我国BDS-PWV同化应用对华东区域天气模式初始场的改善效果。

Abstract: The meteorology is one of the earliest important fields to apply the BDS in. An unprecedented pattern has gradually formed for the comprehensive application of BDS to meteorology with the development of BDS. The construction and application of meteorological industry systems based on BDS ground-based augmentation systems can effectively improve the meteorological observation capabilities of GNSS in China, and also reduce the dependence of current GNSS applications on the GPS and GLONASS. This is of great significance for the development of meteorological application and the support for BDS industrialization. The current advances in the GNSS application in the numerical weather models are reviewed in this paper. The observation error is estimated for real-time inversion of precipitable water vapor (PWV) with BDS, based on the application of BDS in the numerical weather model. Through BDS-PWV assimilation application experiments in regional numerical weather model, the preliminary evaluation of the improvement effect is conducted for BDS-PWV assimilation application in the regional numerical weather model of the East China.

Key words: BDS, PWV, numerical weather model, data assimilation
