COSMIC计划

COSMIC Project

为了获得足够多的地面掩星点资料,用于全球和局部天气预报和大气研究,1997年中国台湾地区和美国联合制定了耗资1亿美元的COSMIC(Constellation Observing System for Meteorology,Ionosphere and Climate)计划。COSMIC是气象、电离层和气候星座观测系统,它包括卫星、地面数据接受和卫星控制站、数据分析中心和数字通讯网络,计划于2005年开始实施。介绍了COSMIC计划产出的历史背景、科学任务及其整个系统的组成,井针对COSMIC和其它LEO(低地球轨道)星座计划,提出了我们应做和正在做的研究工作。

COSMIC (the Constellation Observing System for Meteorology, Ionosphere and Climate) is a joint project between U.S. and Taiwan region of China. The scientific foundation of COSMIC is based on radio occultation (limb sounding) technique for the earth atmosphere and geoscientific objects. The COSMIC constellation is currently planned to be launched in 2005.The components, functions and scientific purposes of COSMIC system, including the LEO satellites, ground data reception and spacecraft control stations, data analysis centers and the data communications networks, are reviewed. As conclusions, some possible research projects related to COSMIC are listed in the final part.
