In WBGT, what does DB stand for?

• A. Dry Bulb
• B. Dew Point
• C. Daily Basis
• D. Damp Bulb

Answer: (A)

In WBGT, DB stands for Dry Bulb. This is the actual air temperature measured by a standard thermometer exposed to the surrounding air, reflecting the sensible temperature without accounting for moisture effects. WBGT uses three measurements—dry-bulb (air temperature), wet-bulb (evaporative cooling, showing humidity effects), and globe temperature (radiant heat)—to assess heat stress. Dew point is a humidity metric, not a WBGT component, and daily basis isn’t related to the index. So the correct meaning of DB is the dry-bulb temperature.
