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

Data

Dependencies

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

Heat exposure estimates for densely populated metropolitan areas in Europe

Exposure estimates are based on air temperature and dew point data modelled with Max Planck Institute for Meteorology Regional Model (REMO). Geographical location of large cities was determined based on EMEP grid level data on total population. If the population density within a grid cell surpassed 200 per square kilometre (i.e. 500000 within a 50 km x 50 km grid cell), the grid cell was considered to include a densely populated metropolitan area. These estimates were used in the assessment Health impacts of urban heat island mitigation in Europe.

Average daily maximum apparent temperature, no. of days when temperature threshold is exceeded, the average exceedance on these days, and the heat sum (95% confidence limits) in April-September averaged over all large metropolitan areas
