GES map heat stress - state 2003

Area-wide map of the Health Effects Screening score (GES) of heat stress in Flanders. The indicator is based on the number of heat wave degree days (°C.day) in Flanders in the year 2003, modeled for the Flemish Environmental Agency (2018). The heat wave degree day (HGD) indicator indicates where and by how many degrees Celsius the threshold values ​​for minimum and maximum temperatures (respectively 18.2°C and 29.6°C), indicated by the FPS Public Health, are exceeded. For each location, the number of heat wave degree days is added up for all days of the year 2003. To create the GES map, we use the HGD map of 2003, a very warm year that is also used as a reference in the study by the Flemish Environmental Agency (2018). It has been decided to work with the map for an extreme year instead of an annual average map, because the health problems mainly occur during these types of summers, and in this way the potential problem locations are properly visualized and not underestimated. The GES classes were defined in this way: GES 2 = 0 - 20 (°C.day) = "fair" ; GES 3 = 20 - 30 (°C.day) = "fairly moderate" ; GES 4 = 30 - 40 (°C.day) = "moderate" ; GES 5 = 40 - 60 (°C.day) = "very moderate" ; GES 6 = 60 - 80 (°C.day) ="insufficient"; GES 7 = 80-100 (°C.day) = "more than insufficient"; GES 8 > 100 (°C.day) = "very insufficient". GES 6 corresponds to at least 60 heat wave degree days, a value that occurs in Antwerp in the year 2003 and for which it is known that there were many victims as a result of heat stress. however, a lower number of heat wave degree days also has negative effects on health. The map can be used to detect potential problem areas for heat stress in Flanders. In addition to air temperature, however, radiation exposure (both short-wave and long-wave), humidity and wind speed are also important factors in determining heat stress and human thermal comfort. The modeling does not take this into account. Locally, the heat stress actually experienced can therefore be higher (for example due to local radiation from, for example, concrete or asphalt pavement) or lower (for example due to shade provided by trees).
