世界首颗静止轨道海洋水色卫星应用研究进展

Advances in the Application Study of the First Geostationary Ocean Color Imager

海洋环境参数和赤潮、绿潮等海洋灾害在一天之内会有明显的变化,需要高频率的观测才能满足监测的需求,极轨水色卫星观测频率低,而静止轨道水色卫星在观测频率方面具有绝对优势。2010年韩国发射了世界上第一颗静止轨道海洋水色卫星GOCI(Geostationary Ocean Color Imager),使小时级时间分辨率的水色遥感成为现实,各国科学家围绕该数据迅速开展了大量研究工作。本文首先介绍了GOCI遥感器的主要参数信息及其数据处理软件,然后综述了GOCI自问世至2016年的主要研究进展,涉及卫星数据处理、产品质量评价、海洋环境探测、海洋灾害监测、海洋动力过程探测、大气探测等方面,以期对我国水色遥感特别是静止轨道水色遥感应用研究提供参考。

Marine environmental parameters and marine disasters such as red tide and green tide can change obviously within a day.Therefore,high frequency observations are required to meet the monitoring needs.The polar orbiting ocean color satellites are relatively lower in observation frequency,whereas the geostationary orbiting ocean color satellites have an absolute advantage in the observation frequency.The first geostationary orbiting ocean color satellite in the world,i.e.the Geostationary Ocean Color Imager(GOCI)was launched by South Korea in 2010,which has made the ocean color monitoring realized an hour level time resolution.Scientists around the world have quickly carried out a large amount research work by using the GOCI data.In the present paper,the major parameters and the data processing software of the GOCI remote sensor are introduced,and then the main advances in the researches of GOCI from its advent to 2016,which involve satellite data processing,product quality evaluation,marine environment and disaster monitoring,marine dynamic process detection,atmospheric sounding,and so on,are reviewed in order to provide references for the application of ocean color remote sensing in China,especially for the application of the geostationary ocean color remote sensing.
