| Prototype - Under Development. Not to be used for operational use. Thanks to Dr. Vince Dimiceli (recently deceased) from ORU for help deriving this product. The Wetbulb Globe Temperature (WBGT) shown is the maximum WBGT for the 24 hour period. Usually it is highest during mid afternoon. The WBGT is a measure of the heat stress in direct sunlight which takes into account; temperature, humidity, wind speed, sun angle and cloud cover (solar radiation). This differs from the heat index which takes into consideration temperature and humidity and is calculated for shady areas. If you work or exercise in direct sunlight, this is a good element to monitor. Military agencies, OSHA and many nations in tropical or hot climate areas use the WBGT as a guide to managing workload in direct sunlight.
