The Corona EU project finished in May 2019. It looked at barriers to opening air quality data and provided some solutions to overcoming these barriers. The partners were Norway (Norsk institutt for luftforskning), Flanders (Informatie Vlaanderen and Vlaamse Milieumaatschappij) and Ireland (Environmental Protection Agency).

Corona project outputs

Corona project complete 28th May 2019 - Wednesday, June 12, 2019

The Corona EU project is complete. Our outputs were:
A report on air quality data open-ness, available under Useful Links (Activity 1 report)
An architecture design for collecting and delivering open data, available under Useful Links
A prototype machine learning tool for quality assessment of air quality data, available under Useful Links
Some new air quality visualisations ( and

We concluded that
1. Air quality data availability is good but users need more metadata about the quality of the data, and need the data to be more interoperable.
2. Service Oriented Architectures are a good fit for open data delivery
3. Machine learning presents many opportunities for air quality data assessment and quality assurance
4. The demand for visualisations of air quality open data matches the demand for the raw data itself
5. The European Data Portal ( Metadata Quality Assessment (MQA) method could be replicated and applied locally by data publishers to improve compliance with MQA
