Radiative cooling Calculator

Radiative cooling is a process by which a material cools down by emitting thermal radiation. This phenomenon occurs when an object loses heat by emitting infrared radiation to its surroundings, typically to outer space.

Where:

• $P$ is the power radiated per unit area (in watts per square meter).
• $\sigma$ is the Stefan-Boltzmann constant (5.67×10−85.67×10−8 W m−2−2 K−4−4).
• $A$ is the surface area of the object emitting radiation.
• $T$ is the absolute temperature of the object (in kelvin).
