Map of analysed ports showing NO₂ and PM₂.₅ concentrations in port areas and surrounding regions

The map shows the ports analysed in the study while the figures present annual mean concentrations for NO₂ and PM_2.5 in port areas compared to their surrounding region. Clicking on a port on the map opens a detailed fiche with additional information.

Additional information

Clicking on a port in the map links to a fiche with additional information specific to that location, including maps showing the 2023 sampling point (SPO) locations, a table with details for each SPO, and EEA air quality maps comparing the port area to the surrounding region, with weighted averages by land cover class.

Methodology

The information on the graphic was compiled from the NO₂ and PM_2.5, European air quality data for 2023 (interpolated data), available form the EEA datahub. The data set provides values for the human health related indicator of NO₂ and PM_2.5 (annual average concentration) at 1km² grid combining monitoring air quality data in a ‘regression-interpolation merging mapping’ methodology and the observational values of the air quality monitoring stations used in the interpolation. It covers Europe for the year 2023. The mean NO₂ and PM_2.5 concentrations "in port areas" were identified as the mean of the values in grid cells within 1km from the port area. The mean NO₂ and PM_2.5 concentrations "in surrounding region" are the mean of the values from the grid cells within 0.5 degrees longitude and 0.5 degrees latitude from the centroid of the port area (port area defined as the polygon classified as “Port areas”, CLC code 123, in CORINE Land Cover 2018).
