What environmental factors affect globe temperature readings?

The correct choice emphasizes the significance of multiple environmental factors in influencing globe temperature readings. Globe temperature is designed to measure the combined effect of radiant heat, air temperature, and air velocity, providing a comprehensive understanding of thermal comfort and heat exposure.

Radiant temperature refers to heat received from nearby surfaces or sources of radiation, such as the sun or heated buildings, which significantly impacts an individual's thermal experience. Air temperature, naturally, influences how hot or cold the surrounding environment feels. Additionally, air velocity, or wind speed, plays a crucial role in convective heat loss or gain, affecting how quickly heat dissipates from or is absorbed by the body.

In contrast, options focusing solely on radiant temperature, only air temperature and wind speed, or only humidity and air pressure neglect the importance of the holistic interaction of these various factors. By studying globe temperature, practitioners can make more informed decisions regarding comfort and safety in diverse environments, taking all relevant influences into account.
