This directory contains the (interpolated) population weighted daily mean air pollutant concentrations (PM10, PM2.5, NO2, O3 and BC) and population weighted daily maximum 8-hour mean per Belgian zipcode.
Concentrations are in µg/m3.
For NO2 and O3 data are available for the period 1995-2023
For PM10 2000-2023
For PM2.5 2008-2023
For BC 2011-2023
Concentrations are calculated using the 4x4 km2 RIO ( https://www.irceline.be/en/documentation/models/models?set_language=en) interpolated concentrations based on an area and population weighted average: for every RIO 4x4 km2 grid, the area of a zipcode that overlaps with that grid is calculated. The population weighted average concentration for a zipcode is then calculated using the gridcel concentrations and population in the overlapping area.
The area weighted average concentrations, is available in the folder "not_pop".
