In WBGT, what does GT stand for?

• A. Globe Temperature
• B. Global Temperature
• C. Ground Temperature
• D. Gas Temperature

Answer: (A)

The key idea is that WBGT uses three measurements to capture different aspects of heat: air temperature, humidity/evaporation, and radiant heat. GT stands for Globe Temperature, which comes from a black globe thermometer that absorbs radiant heat from the sun and surrounding surfaces. This measurement reflects how radiant energy contributes to the overall heat stress a person feels, separate from the air temperature (dry-bulb) and humidity effects (wet-bulb). The other options don’t fit WBGT terminology: Global Temperature isn’t the term used in this index, Ground Temperature would measure soil temperature, and Gas Temperature isn’t the component used for assessing heat stress. So Globe Temperature is the correct meaning of GT in WBGT.
