The reflectivity ( bond albedo ) of the moon is 0.12 , or 12 percent . The cloud-free earth 's is 0.29 .
月亮的反射率(邦德反照率)仅为0.12,或12%,而无云地球的对应值是0.29。
The spacecraft mapped shackleton crater with unprecedented detail , using a laser to illuminate the crater 's interior and measure its albedo or natural reflectance .
The study also included important parameters concerning the surface albedo ( how much light is reflected away by the planet 's surface ) and the humidity of the atmosphere .
该研究还考虑到有关地表反照率(地球表面反射出去多少光线)和有关大气湿度的重要参数。
Shrinking ice and snow cover across the arctic has sabotaged the far north 's " albedo " -- one of the earth 's tried-and-true methods of chilling itself and maintaining a relatively stable global climate , according a new study that appeared this week in nature geoscience .
