Testing microsensors for air quality measurements in Bergen

Since September the municipality of Bergen has mounted 15 microsensors at their official measurement stations at Danmarksplass and Klosterhaugen to test the quality of the different air quality sensors. Five of them will now be installed at Skjold school, Lyngbøtunet, Åsane center, Nordahl Grieg high school and Indre Arna kindergarten.

More sensors will be mounted in Bergen in spring 2021. The aim is to install two sensors in each city district to obtain a better picture about the air quality over the whole municipality.

You can read more about this on the web pages of the municipality of Bergen (in Norwegian).

Kick-off for measurements in Oslo and Bergen

We are preparing air quality measurements with low-cost sensors in Oslo and Bergen. In mid-August we started calibrating the instruments at the monitoring stations Kirkeveien and Sofienberg in Oslo. We deployed 25 low-cost sensors from different suppliers. First, they have to be calibrated before they can be deployed over the whole city. In Oslo we collaborate with Ruter, who provide us access to their bus/tram/metro shelters for delpoying low-cost sensors.

At the same time we are also deploying low-cost sensors for calibration at the monitoring stations Danmarks plass and Klosterhaugen in Bergen. Here, we will test 15 instruments before they will be used to complement the air quality monitoring network in Bergen.

Once the calibration periods in Oslo and Bergen are completed, the iFLINK project will use these low-cost sensors to set up a dense sensor network in Bergen, Bærum, Drammen, Kristiansand and Oslo during spring 2021.

The iFLINK project is collaborating with several ongoing European projects and activities. One of them is sensEURCity, a project coordinated by EU’s Joint Research Centre in Ispra, Italy. Here, Oslo is a cooperating city, together with Antwerp, Belgium and Zagreb, Croatia. Via the sensEURCity project we have 34 AirSensEur low-cost sensors available that will be used in Oslo until March 2021. In this project we also cooperate with Oslo Bysykkel, who are providing their bicycle racks for deploying our instruments.

New report on recommendations when purchasing a sensor system

NILU has published a report on specifications for air quality monitoring sensor systems.   This report explains technical terms related to measuring performances, as well as providing recommendations and requirements in connection with preparation of tenders. The report goes through existing instrumentation for air quality measurement in Norway and current legislation on the subject. It mentions possible applications for new measurement technologies. An overview of metrological terms with explanations gives the reader basic knowledge necessary to interpret instrument specifications. The report identifies some important parameters related to the quality of sensor systems.
