GES air quality map - state 2017
This is the original input data that has not yet been converted to Cloud-Optimized Geotiff. Area-wide map of the Health Effects Screening score (GES) of local air quality in Flanders. The indicator is based on the annual average NO2 (nitrogen dioxide) concentrations (Vlaamse Milieumaatschappij 2017), which was modeled with the RIO-IFDM-OSPM model chain. This pollutant was taken as a basis because of its large spatial variation, strong link with local emissions and well-documented health effects. The NO2 concentrations were then divided into classes using the Dutch Health Effect Screening (GES) methodology, which provide an insight into the potential health effects of air pollution by NO2, as a first indication of local air quality. Naturally, other pollutants (such as particulate matter or ozone) are also important in the further analysis and assessment of local air quality. The GES classes were defined in this way: GES 1 = 0-10 µg/m³ annual average NO2 = "good" ; GES 4 = 10-20 µg/m³ annual average NO2 = "moderate"; GES 6 = 20-30 µg/m³ annual average NO2= "insufficient", GES 7 = 30-40 µg/m³ annual average NO2= "more than insufficient", GES 8 >40 µg/m³ annual average NO2= "very insufficient". From GES 6, the health guideline value as recommended by the Agency for Care and Health (maximum 20 µg/m³ annual average NO2) is exceeded, but lower concentrations also have negative effects on health.
