temperatuur, mille juures peab olema ümbritsevaga termilises tasakaalus olev must keha, et dubleerida halli kehaobjekti täheldatud intensiivsust kiirgussagedusel
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
measure of the intensity of electromagnetic energy coming from a source
Eelkõige on eredustemperatuur temperatuur, mille juures must keha peaks olema, et dubleerida halli keha objekti täheldatud intensiivsust sellel sagedusel. Terminit „eredustemperatuur“ kasutatakse raadioastronoomias, planeediteaduses, materjaliteaduses ja klimatoloogias.
In particular, the brightness temperature is the temperature at which a black body 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, materials science and climatology.
