基于静止卫星的晴空背景场快速构建算法

The Rapid Construction Algorithm of Clear Background Based on Geostationary Satellite

静止卫星具有非常高的时间分辨率,是大气气溶胶实时监测的重要手段.背景场合成方法是静止卫星气溶胶反演中最常用的方法,因此快速高效地构建晴空背景场对于提高静止卫星大气实时监测能力具有十分重要的意义.针对新一代静止卫星Himawari 8的多波段和高频率观测的特点,提出并实现了一种晴空背景场构建算法.利用2015年10月15日至2015年11月1日的Himawari 8数据进行晴空背景场的构建实验,结果表明该系统能够满足晴空背景场的快速构建,并且为静止卫星在大气气溶胶监测方面的应用提供支持.

The geostationary satellite has a very high time resolution, which is an important means for real-time monitoring of atmospheric aerosols. Background field synthesis is the most common method in the a geostationary satellite aerosol retrievals, so to improve the geostationary satellite real-time atmospheric monitoring capability fast and efficient construction of clear background field has very important significance. In this paper, the characteristics for a new generation of geostationary satellite Himawari 8 multi band and high frequency observations, is proposed and implemented a clear background field construction system. According to the data in Himawari 8 from 15 October 2015 to 1 November 2015, the results show that rapid construction of the system can satisfy the clear background, and provide support to help maintain application of geostationary satellite in the monitoring of atmospheric aerosol.
