Air pollution is a global challenge and a major concern in major cities around the world. In order to set up and maintain an acceptable level of ambient Air Quality Monitoring System (AQMS) specific measures need to be taken. While networks of fixed measurement stations have been a quite accurate solution during the past years, the low spatial resolution of the collected data does not allow the assessment of the spatial variability of pollutants in detail while other drawbacks include their large size, high price and laborious maintenance.
It has been reported that an increase in network size of fixed stations can lead to increased complication, exponentially growing costs and effort for data analysis and visualization. Thus, engaging citizens into being part of a collaborative system of the emission monitoring infrastructure can contribute towards this direction, bringing different complexities, issues, challenges and opportunities than the static-based solution. During the CAROLINA project, we aimed to explore the current state of the art in air quality monitoring approaches and consider the inclusion of citizens into an open and collaborative process for an enriched air quality monitoring system. Thus, in order for citizens to become a vital part of this system and contribute towards the reduction of urban air pollution, the motivation and the way to attract and engage them was explored. Finally, based on the discussion around current and past projects with similar scopes to CAROLINA from the city of Istanbul, Turkey and the findings of the literature review, further opportunities and suggestions towards the deployment of such a system are provided.
The aims of the EPFL’s task can be summarized to:
- Exploration of the current state of the art in next generation monitoring techniques
- Consideration of the open collaboration approach for AQ modelling and monitoring
- Analysis on what should be the motivation, what should attract and how to engage citizens to actively contribute towards the reduction of urban air pollution
- Examination of the city of Istanbul as a specific case study based on the findings
Two important directions were discussed. The first one described the state-of-the-art and identified the main issues that should be taken into consideration by policy makers, researchers and practitioners during the first stages of the design and deployment a network of sensors. It is an important guide that not only categorises challenges and caveats but also identifies substantial opportunities to maximize the success rate of such a system. Compared to earlier approaches, a hybrid system is suggested the ideal solution using the latest powerful data fusion techniques and technological advancements. Since the low-cost sensors are still not flawless in terms of accuracy, calibration and collection of high-quality data should be the primary goal.
The second direction that is related to the engagement of the citizens to participate in an AQMS identified that some of the main concerns of the citizens’ participation include privacy, data quality and energy efficiency issues. Additionally, it is important to maintaining their engagement and participation throughout the data collection process is of major importance and can be guaranteed by quality feedback, economic or other incentives and technological support. Finally, as communities have been demanding a greater role in decision-making that affects their lives it is vital to communicate the results of such participation in a clear way.
The final part of the project discussed how the findings described above combined with the experience from current and past projects in the city of Istanbul, Turkey can be a unique opportunity for the successful deployment of a low-cost sensor system in a city like Istanbul.
