Brightness Temperature

Brightness temperature is a way to measure how much thermal radiation an object emits, usually in the context of weather and astronomy. It reflects the object's temperature based on the intensity of the radiation it releases, particularly in the microwave and infrared wavelengths. Essentially, brightness temperature helps scientists understand how hot an object is by evaluating the energy it radiates. For instance, in satellite imagery, it can indicate cloud temperatures or surface temperatures on Earth and other celestial bodies. Understanding brightness temperature aids in weather forecasting and studying climate variations.
