Air Quality pilot with Hopu

Pilots in Mechelen & Bruges


How can we monitor and improve air quality in our cities using open data?

The cities of Mechelen and Bruges are working together with HOPU on air quality data collection. People are nowadays protesting almost weekly for climate change and cleaner air. Air quality enhancement requires a fine monitoring and continuous feeding and updating of the datasets with data obtained from open data portals and sensors deployed around the city, as recommended by the World Health Organization (WHO) to determine air quality index (AQI).

As shown in the next graph, the evolution of for example PM10 has been reduced but we are still not reaching the recommended WHO values.

The first devices will be installed in the second week of july. Sensors are placed at 7 locations in different circumstances to find differences in concentrations with a lot of traffic, green spaces in the city and rural area next to the city. Also a weather station will be placed to find correlations with high temperature, rainfall or wind. 


In addition, it is not only necessary to monitor air quality but also to enable tools and services for its maintenance/calibration to guarantee data quality and data exploitation through artificial intelligence / data mining algorithms. Thanks to the collaboration with HOPU the cities will be able to carry out all of these requirements using FIWARE platform (where Hopu is a gold member) is  to integrate existing data sources and gases/particle matter sensors (Smart Spot) and use their data analytics capabilities for air quality. 


Complementarily, processed data is visualized on HOPU’s dashboard to monitor and analyse metrics/indicators based on IEEE and ITU-T standards to improve informed decision making for cohesive proposals, ideas and actions that lead to livable, healthy and sustainable cities
