Mean radiant temperature
Mean Radiant Temperature (MRT) is the uniform surface temperature of a black enclosure with which an individual exchanges the same heat by radiation as the actual environment considered. It describes the radiant environment for a point in space. Distance to a source affects the temperature that is felt. For instance, if the sun is setting, turning to night, you may feel coolness, although the air temperature is unchanged at that moment.
Additional recommended knowledge
Radiant temperature can be approximated by a black-globe thermometer which measures the effects of radiant and convective heat transfer.
