* Following WP3.7-work and WP4.3-screening, DRF will be based on the PHEWE project, which investigated the acute health effects of weather in 15 European cities and provided both pooled estimates (Mediterranean region  and North-Continental region) of the impact of heat on mortality (Michelozzi et al. 2007; Baccini et al. 2008). DRFs are based on a linear threshold model.  Heat exposure is defined as follows: °C Daily maximum Apparent Temperature over threshold temperature, warm season (April-September).
+
*Meta-analytical estimates are based on studies in the following cities:
−
* DRF available for: mortality due to natural causes, CVD mortality and RESP morality.
+
**Mediterranean cities: Athens, Rome, Barcelona, Valencia, Turin, Milan, Lubljana
−
* Assumption: Threshold and the DRF differ for the Mediterranean region and the North-continental region; we therefore assume that the EU-27 can be divided into two larger regions with different DRF.
+
**North-continental cities: Prague, Budapest, Zurich, Paris, Helsinki, Stockholm, London, Dublin
−
* Assumption: Temperatures above thresholds will only occur in warm season (April-September)
+
*Based on climate and mortality data for the period 1990-2000
−
* Assumption: DRF for mortality due to natural causes can be applied to total mortality
+
*Exposure assessment: daily maximum apparent outdoor air temperature (nearest airport weather station of each city)
