The Air Pollution Comparator is a web application designed to visualize and compare air quality data for different cities and locations. The goal of the project is to provide a simple interface where users can search for a city, study its current air pollution values, and compare multiple places using visual indicators and charts.

The application focuses on three main air quality indicators: AQI, PM2.5, and PM10.

• AQI gives a general indication of air quality
• PM2.5 and PM10 represent particulate matter concentrations

These values are useful because they allow users to understand not only whether the air quality is good or bad, but also which pollutant contributes to the situation.

This project has been realized by the students Sara Maddalena Piccinini, Leonie Rank and Bartolomé Sala in June 2026 as part of the course Data Ethics and Open Data at the UAS Technikum Wien as part of the StudyATHome hub. This course is also part of the project IoCEST – Internationalisation of the Curricula in Engineering, Environmental, Smart Cities and Sport Technologies which has been funded by the City of Vienna.
