【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.
[Abstract]:The microwave radiometer (MRM) carried by Chang'e 1 CE-1 has obtained the data of microwave brightness temperature (TB) throughout the month, but the large amount of information contained therein (such as the reflection of the earth) has not been excavated. The reflection of the earth is an important source of heat affecting the terabytes at night on the surface of the moon. Is also an important way to study global climate change. According to the characteristics of synchronous rotation of the moon, Based on the CE-1 MRM data, the bright temperature information of Chenghai on the front of the moon and highlands in the low latitude zone under the influence of the earth's reflection is preliminarily extracted. The results show that the brightness temperature of the Chenghai area is mainly between 1.01.6 K, The highlands in the low latitudes are between 0.2 and 0.6 K.
