WebPassive Radiative Cooling is a natural phenomenon that only occurs at night in nature because all nature materials absorb more solar energy during the day than they are able to radiate to the sky. At night, the surrounding environment cools the material to a temperature that is below the dew point or below freezing to form frost.
