Scope

What is the location-specific daily heat exposure in Europe?

Heat exposure is defined as the location-specific daily maximum apparent temperature (AT) (i.e. humidity-adjusted temperature) above an area-specific threshold value.

Definition

Dependencies

• Ambient air temperature in Europe
• Ambient air dew point temperature in Europe
• Urban heat island effect in Europe
• European climate scenarios
• Apparent temperature threshold for the ERF for heat exposure and mortality:
  • Mediterranean region: 29.4 (95% Cl 25.7-32.4)
  • North-continental region: 23.3 (95% Cl 22.5-24.0)

Unit

°C

Formula

Heat exposure = Maximum daily apparent temperature - apparent temperature threshold

Apparent temperature (AT) = -2.653 + 0.994 Temp + 0.0153 (Dew)2
*Temp = air temperature
*Dew = dew point temperature
