静止卫星的海洋水色观测计划

The Introduction of International Plans in Monitoring Ocean Color on the Gestational Satellites

海洋现象的时空尺度分析表明目前以极轨方式运行的海洋水色卫星遥感不能完全满足沿海及海岸带地区管理和研究的需要。采用静止卫星作为水色遥感观测的平台对沿海和海岸带进行高频率的遥感观测,可以满足海岸带生物物理过程研究和调查所需观测频度的要求,有利于确定潮汐混合条件,建立新的模型,探测短时间尺度的生物物理现象,改变现有的海岸带管理方式,实现海岸带资源的科学管理,具有极轨卫星不可具备的优势。本文简单介绍了韩国预计发射的静止水色成像仪KGOCI和美国GOES-R卫星计划的HES-CW,同时希望我国能早日研制发射出自主的静止水色观测卫星和传感器,为我国漫长的海岸带监测提供利剑。

The analysis of the spatial and time scales of ocean phenomena and processes shows that polar-orbiting sensors can＇t totally satisfy the demand of coastal water environment research. Geostationary satellites as the ocean color monitoring platform have the distinctive advantages as compared with the current sun-synchronous polar orbiter observations, which can focus on an area of interest for an extended period to satisfy the demand of coastal water biophysical progress research and survey. It will be helpful to validate tidal mixing terms and to set up new coastal ecosystem models, detecting the short term biophysical phenomena. And it will change the manners of coast resources management as more scientific ways. The GOCI of Korea and HES-CW of America are introduced in this paper. These can be used for reference by China.
