This map contains data of clouds on the East Coast of the United States with the exception of the New England territories. This map includes a menu finding the amount of clouding up total, changing total, clouds total, threatening total, and cloudy total. The total amount is in decimals, which is because of the "breaks" feature of the index.
Clouds have a complex and important role in regulating the climate because they can both cool the planet by reflecting sunlight back into space and warm it by trapping heat radiated from the Earth's surface. The overall effect of clouds varies depending on their type, altitude, and the amount of sunlight present.
