Cloud cover (also known as cloudiness, cloudage or cloud amount) refers to the fraction of the sky obscured by clouds when observed from a particular location. A planet surrounded by cloud cover would become an arctic wasteland while a planet without cloud cover would become a waterless desert where even reptiles are incapable of surviving and thriving (due to an excessive amount of greenhouse gasses and solar radiation that would develop).
