摘　　要：嫦娥一号(CE-1)搭载的微波辐射计(MRM)获得了全月微波亮度温度(TB)数据,但其中包含的大量信息(例如地球反照等)尚未被挖掘.地球反照是影响月表夜晚TB的重要热源,也是研究全球气候变化的重要途径.根据月球同步自转的特点,本研究基于CE-1 MRM数据初步提取了地球反照影响下的月球正面的澄海和低纬度带的高地地区的亮温信息.结果表明:澄海地区的亮温主要在1.0 1.6 K之间,低纬度带的高地地区则在0.2 0.6 K之间.The Microwave Radiometer （MRM） on board the Chinese Chang＇E-1 （CE-1） Orbiter has acquired the microwave brightness temperature （TB） data of the Moon on a global scale. However, information such as the earthshine effects contained in TB data had not been fully explored. As a heat source of the Moon, the earthshine may have an important effect on the TB of the Moon during the Lunar night-time and might also help to study the global climate Change of the Earth. Based on the fact that the Moon is in synchronous rotation with the Earth, the effects of earthshine on TB at Mare Serenitatis and the highland areas are studied using the CE-1 MRM data. It has been found that the TB ranges from 1.0 to 1.6 K at Mare Serenitatis and 0.2-0.6 K in the highland area.
