Scientists Watch Dark Side Of The Moon To Monitor Earth's Climate

Summary:
Scientists have revived and modernized a nearly forgotten technique for monitoring Earth's climate by carefully observing "earthshine," the ghostly glow of the dark side of the moon. Earthshine measurements are a useful complement to satellite observations for determining Earth's reflectance of sunlight, an important climate parameter. Long-term observations of earthshine thus monitor variations in cloud cover and atmospheric particles known as aerosols that play a role in climate change.
