Likewise, seasonal vegetation, clouds, aerosols, snow and ice cover, and even faint atmospheric emissions (such as airglow and auroras) change the way light is observed in different parts of the world. The principal challenge in nighttime satellite imaging is accounting for the phases of the moon, which constantly varies the amount of light shining on Earth, though in predictable ways. The NASA group has examined the different ways that light is radiated, scattered and reflected by land, atmospheric and ocean surfaces.
The new global composite map of night lights was observed in 2016.
