It is possible to convert brightness temperature of Earth surface (K) to the actual temperature?
Is there any formulae for such conversion?
Thanks in advance!

Brightness temperature is a measure of the intensity of radiation emitted by a celestial object, such as a star or planet. It is typically expressed in units of kelvins (K) and is related to the amount of energy emitted by the object.
Brightness temperature is measured using specialized instruments, such as telescopes and radiometers, which detect and measure the electromagnetic radiation emitted by an object. The detected radiation is then converted to a temperature value using mathematical equations and calibrations.
Brightness temperature is a measure of the radiation intensity emitted by an object, whereas actual temperature is a measure of the average kinetic energy of the particles within the object. In some cases, the two may be closely related, but in others, such as with stars and planets, there can be a significant difference between the two values.
The brightness temperature of an object can be affected by a variety of factors, including the object's size, composition, and distance from Earth. Other factors, such as atmospheric conditions and the sensitivity of the measuring instrument, can also have an impact on the measured brightness temperature.
Studying brightness temperature can provide valuable information about the physical properties and behavior of celestial objects. It can also help scientists better understand the processes that occur within these objects, such as nuclear fusion in stars, and provide insights into the overall structure and evolution of the universe.
