3 Our motivation In 2011, premature deaths in Europe were attributed to air pollution Europe: annual cost of health impacts for mortality/morbidity, trillion USD Current situation Compliance & regional monitoring: Few monitoring stations Information systems: low awareness No real-time data where people are Absence of personalized data: - what does air quality mean to me? - what can I do? Citi-Sense Goals Developing Citizens Observatories with a variety of micro sensors Integrating data analysis across data types and cities Empowering citizens to influence community policy & decision making The Guardian

4 CITI-SENSE aims CITI-SENSE Development of sensor based Citizens Observatory Community for improving quality of life in cities Contribute to and participate in environmental governance Support and influence community and policy priorities and decision making Contribute to the Global Earth Observation System of Systems (GEOSS) Technological enabler: ICT, sensor devices.

5 Citizens observatories Communities of users that will share technological solutions, information products and services, and community participatory methods, thus complementing established environmental data and information systems and improving local environmental decision making.

6 Perspectives Users Technologies:

8 Monitoring air quality where people are Static sensors located in kindergartens Mobile sensors carried by volunteers Data fused maps, air quality where you are Exposure to pollution, personalized information

9 Questionnaires and mobile apps to understand air quality perception Are you interested in AQ? Not interested Little interested Very interested Interested Opinion on air quality and its effects on health Accessibility and usefulness of air quality information Empowerment, who can improve air quality? How? How can we improve air quality information to the public GIS-survey Perception where you are People as sensors

10 What data quality do we need? Relative Requ uired Data Quality Higher Lower Ambient air monitoring network and compliance Supplement Air Monitoring Network Community based monitoring and Screening Education and Qualitative monitoring ost Relative Co Adapted from: Snyder et al. Env. Sci. Tech Relative Deployment Density

11 Low-cost sensor technologies New opportunities Observations at high resolution Monitoring at points of interest Citizen engagement Personalized data Challenges Data quality: error characteristics, long-term measurement capability Maintenance of large sensor platform networks: sensor failures, data storage, data treatment, recalibration. Privacy and security: personal sensors (linked with position data)

12 Challenge: Instrument performance and uncertainty Laboratory & Field Validation and Calibration Provide accurate and scientifically defendable information, fit for purpose. Otherwise data is useless.

13 Performance of low cost sensor platforms Extensive evaluation of commercial low-cost platforms against CEN reference method analyzers Results NO 2 : In laboratory r 2 = 0.9 In the field, the highest r 2 was out of 24 pods had r 2 <0.4 7 out of 24 pods had r 2 <0.2 The performance varies: location, meteorological conditions, degradation of the sensor

14 Sensors: What data quality do we need? Data quality objectives for ambient air quality assessment defined in the AQD 2008/50/EC DQO Fixed measurements Indicative measurements SO 2, NO 2, NO x, CO PM10, PM2.5 O 3 15% 25% 15% 25% 50% 30% High Medium Coarse Information Signal #1 Signal #2 A 1 A 2 High Medium Low Low A 1 (t) & A 2 (t) in the same segment -> Match score = 1 A 1 (t) & A 2 (t) not in the same segment -> Match score = 0 Average for 24 pods ( to ) Pollutant NO NO 0.8 O CO 0.4 PM PM Match

15 Questionnaires Knowledge and views

16 Air quality in your city?

17 Air quality in your city?

18 Air quality in your city?

19 Air quality in your city?

20 A map for your city? Create a static basemap for your city Retrieve crowdsourced sensor observations at each hour (other data can also be used) Modify the basemap with latest observations using geostatistical data fusion Final result - hourly maps with the current best guess for the NO 2 /PM 10 /PM 2.5 concentrations at all locations Lahoz, W. A., and P. Schneider (2014), Data assimilation: making sense of Earth Observation, Front. Environ. Sci., 2(16), 1 28, doi: /fenvs

21 A map for your city? Examples - data fusion-based surface concentration field of NO 2 for Barcelona, ES, and Oslo, NO, at 100 m spatial resolution.

22 Platform & data flows Data Providers Proprietary Access Citi-Sense Platform End Users Apps Web Portals Widgets Standardisation Service s GEOSS

23 How open are the data and tools? Data (processed) and information are open to everyone Open source apps and widgets with good documentation for further use (SMEs, students, universities,..) Tools are easily adjustable (authorities)

24 Citizens Observatories Toolbox

25

26 Public front-end Air quality visualisation portal multi-cities, multi-input Citizens observatories portal methods and tools Questionnaires/Apps AQ literacy, CityAir App Where-to-get sensors Sensor output evaluation statistical package AQ information maps Public spaces - user evaluation toolkit Educational activities for schools (ages 6-18)

27 Engaging with the public

28 Ljubljana Active dissemination e.g. leaflets, baloon days, and much more Focus group discussions with LEO volunteers Collaboration with schools Committed participants (Mayor also hosting one AQMesh)

29 Ostrava Citizen collaboration 3 biomonitoring campaigns - citizens Monitoring campaign -cyclists Networking with community-driven initiatives Educational program for schools Kindergartens Primary schools Open days and Earth days Public co-creation events Public seminars, conferences, open days Interviews - citizens, authorities, NGOs Awareness about air pollution Flyers, media campaigns, stands National and international events

30 Haifa Anual Project in elementary schools and junior-high Measurements Perception Understanding air pollution Panel about air quality in Haifa, with representatives of all stakeholder groups. Public air pollution info portal

31 Barcelona CitizenSqKm & ispex collaboration external training in environmental monitoring networking with community-driven initiatives Public Events, e.g. ECSA conference Citizen Safari Crowd & The Cloud Social and traditional media campaigns CityAir app promotion CivicFlow questionnaire dissemination

32 Edinburgh Jointly funded workshop Use of low-cost sensor technology to monitor air quality & engage citizens discussion sessions with sensors developers, local Authorities, researchers and other stakeholders Local Advisory Committee convened Representatives from local authority, NGO, regulator and AQ researcher Engaging with cyclists and general public Flyers, media campaign, street team CityAir app promotion CivicFlow questionnaire dissemination Local authority engagement to deploy sensors in city

33 Belgrade AQ monitoring: 34 pods, 25 AQMesh & 9 EB AQ literacy questionnaire 55% and more are very interesed in air quality For 60% and more air quality in Belgrade is very bad 50 volunteers personal AQ monitoring for 1 week Marketing events, meetings & disscussions with stateholdes Activities for and with schools Collaboration with Municipality, Serbian EPA, etc Contribution at media campaing Participation at conferences

34 Vienna CitizenSense & University collaboration training in environmental monitoring exchange about crowd sourcing of environmental data Children as Scientists CityAir app promotion CivicFlow questionnaire dissemination

35 Oslo Air quality monitoring in kindergartens 17 kindergartens from December 2015 Additional 35 kindergartens in June 2016 Citizen participation in monitoring air quality 40 volunteers carrying a LEO unit for 1 week Campaign Colour the Oslo air to promote the CityAir app Co-creation events: Focus Groups, Interviews and Open Events involving authorities, NGOs and citizens Creating awareness about air pollution Flyers, media campaigns, stands Participation in the European Mobility Week

36 In summary: Public engagement in environmental governance Technologically enabled Citizens Observatories allow: Involvement of different actors/stakeholders - better results (decision-making, implementation) Different forms of public engagement from collecting contributions only to active participation in problem framing, design, data collection, interpretation and implementing measures Technologies: fit for purpose
