WebApr 14, 2024 · The cloud-top brightness temperature can reflect the radiation emitted into space from the cloud-top and cloud-free or cloudless regions of the Earth’s surface. It is commonly referred to as black body temperature (TBB) . The lower is TBB, the higher the cloud-top height will be, which indirectly reflects the intensity of TC activity. Brightness temperature or radiance temperature is the temperature at which a black body in thermal equilibrium with its surroundings would have to be in order to duplicate the observed intensity of a grey body object at a frequency . This concept is used in radio astronomy, planetary science and materials science. The brightness temperature of a surface is typically determined by an optical measurement, for …
