| 摘 要： | 由中国“嫦娥一号”(CE-1)微波辐射计对月球虹湾地区观测时刻相对应的太阳入射角与方位角, 由极点球面坐标系与月球观测点局部坐标系的转换关系, 得到CE-1 对月球虹湾区域(Bay of Rainbow, 拉丁文Sinus Iridum)观测的当地时间. 采用CE-1 微波辐射计观测数据, 得到月球虹湾地区当地不同时间的辐射亮度温度(Tb)变化分布. 由月表三层模型的热辐射传输理论, 结合CE-1 微波辐射计19 与37 GHz 通道的Tb 数据, 反演得到月球昼夜不同时段虹湾地区表面月尘层与月壤层的物理温度变化, 分析了影响虹湾地区月表面物理温度的主要因素.

| Abstract: | Based on the incidence and azimuth angles of solar illumination during observations by Chinese Chang'E-1 lunar satellite,the brightness temperature(Tb) observed by CE-1 multi-channel radiometers,especially at the Sinus Iridum(i.e.Bay of Rainbow) area,are collected at different lunar local time from the transformation between the principal coordinates and local coordinates at the observation point.It shows the Tb distribution and its diurnal variation.Based on the radiative transfer modeling of three-layer l... |
