Air Quality Sensing
Developing a platform for integrating Citizen Science measurements and authoritative air quality data
Over the last few years, the Joint Research Centre (JRC) of the European Commission has worked extensively on ways to use lower cost sensors to complement authoritative air quality data (e.g. the AirSensEUR open hardware/software/data platform). JRC built upon this experience and initiated a new activity involving three European cities as pilot sites (Antwerp, Oslo, and Zagreb), where 85 sensor boxes will be deployed through dedicated measurement campaigns.
To support their research, JRC needs a data management platform to collect both the data of low cost air quality sensor boxes and the authoritative data measured by the official agencies. This data platform will be based on the INSPIRE-compliant interoperability standards OGC Sensor Observation Service and OGC SensorThings API specifications.
52°North will integrate a data validation process based on R/Shiny as well. It calibrates the low-cost sensor data measurements according to the official measurements. In order to enable users to view and explore the collected data, data visualization functionality will be provided. This will be based on the Helgoland Sensor Web Viewer.
In 2019, 52°North focused on requirements analysis and architecture development. This mainly comprised the design of a data import workflow, a concept for hosting the AQSens Data Platform, and the analysis of approaches for integrating a data validation process based on R/Shiny. This was complemented by the deployment of first components, i.e. the 52°North Sensor Web Server modules for supporting the OGC Sensor Observation Service and OGC SensorThings API standards.
