WebRadiative cooling. Earth's longwave thermal radiation intensity, from clouds, atmosphere and surface. In the study of heat transfer, radiative cooling [1] [2] is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation .

In meteorology, cloud forcing, cloud radiative forcing ( CRF) or cloud radiative effect ( CRE) is the difference between the radiation budget components for average cloud conditions and cloud-free conditions. Much of the interest in cloud forcing relates to its role as a feedback process in the present period of global warming. [1]

WebSuch radiation can be divided into: Longwave; Medium wave; Shortwave. In this case, the wavelength depends on what temperature the source itself emits. The higher the temperature, the shorter the radiation wave will be, but at the same time it will be more intense. For the human body, short-wave radiation is considered the most dangerous.
