What it is
An EO-based service that provides indicators of atmospheric pollution over port areas and neighbouring urban/coastal zones. It focuses on pollutants relevant to air quality regulations and port emissions, such as nitrogen dioxide (NO₂), sulphur dioxide (SO₂), carbon monoxide (CO) and aerosols.
What questions does it answer
What are the spatial patterns and trends of air pollution over the port and its surroundings?
Are there hotspots linked to specific activities (e.g., berths, terminals, road access)?
How do observed patterns relate to regulatory thresholds and mitigation measures?
How it works (high level)
The service uses satellite-based atmospheric observations, optionally combined with local air quality measurements where available, to derive pollution indicators over and around the port. Time-series analysis helps identify persistent hotspots, temporal trends and potential effects of mitigation actions. Outputs can be provided as maps, aggregated indicators and time-series graphs.
Role in the EO4PORT roadmap
This product responds to ports’ requests for better evidence on emissions and air quality in support of environmental management, reporting obligations and communication with surrounding communities.
