EARTH SCIENCE > SPECTRAL/ENGINEERING > MICROWAVE > BRIGHTNESS TEMPERATURE
The apparent temperature of the surface assuming a surface emissivity of 1.0.
Setting the emissivity to one is equivalent to assuming the target is
a blackbody, so the brightness temperature is defined as the temperature
a blackbody would be in order to produce the radiance perceived by the
