The air quality data from the sensors is sent to a common database. A team of researchers will check the data collected, store them, analyze them, and use them to further scientific research and, possibly, policy making in the area of protecting our environment and health. 

The research team will also use the data to understand better what works/doesn’t work for involving citizens in these issues and how to improve the operation of the project.

You can see the collected data using the map below. After you select Oslo in "Location", you can see the latest data collected by Static sensor units located in kindergartens and streets, the Mobile sensor unites carried by volunteers and people's air quality perception collected with the CityAir app.

You can select what type of sensors you want to see in "Layers". There you can also select the "air quality map" to see how is the APIN in places where there are not sensor units. The map is created using data fusion techniques merging the data from an air quality model (EPISODE) and the data from the Static sensor units.

The data is displayed using the Global Air Pollution Indication (APIN) that takes into account all the pollutants measured. If you are interested in a particular pollutant you can select it by clicking on "Filters". Be aware that the Mobile sensor units only measure NO, NO2 and O3. In "Filters" you can also see how people has perceived the air quality in the last month, last 7 days and last 24 hours.

If you are one of the volunteers carrying a Mobile sensor unit (LEO) you can see the data you have collected by clickin on "For LEO users", selecting "see your track" and tiping in your User ID. The User ID is the one you have used in the ExpoApp. 

You can see how the air quality is overall Oslo by clicking "City APIN". You can see how many sensors have low or high air pollution.

Survey results

To help us understand what citizens think about air quality in Oslo, we are conducting an online survey. So far over 300 respondents have completed the survey, and we would therefore like to show you some preliminary results.  

How interested are you in air quality in general?

One of the first questions that we ask in the survey is how interested the respondent is in air quality. As shown in the figure below, the preliminary results indicate that the citizens of Oslo have high interest in air quality. 



How would you describe the air quality in Oslo in general?

Interestingly, there is almost an equal number of respondents that find the air quality in Oslo to be good, as respondents finding the air quality to be poor. The underlying cause of this finding might be the fact that some areas in Oslo are much more heavily polluted than others. 

What steps do you think you would personally take to help improve air quality in Oslo?

We also asked the respondents what steps they would personally take to improve air quality in Oslo. The results show that the large majority of the respondents are willing to either use more environmentally-friendly means of transportation, and/or use more environmentally-friendly systems at home. 

In the following weeks, we will continue to publish new results from the survey.
