NILU - Norwegian Institute for Air Research has commissioned a survey of local air quality in Hønefoss on behalf of Ringerike municipality. The survey program started in June 2018 and was completed in May 2019. The measurements were carried out to obtain the knowledge base for a new town plan in Hønefoss.

The measurement program included measurement of particulate matter and nitrogen dioxide as well as meteorological parameters such as temperature, pressure, relative humidity and wind.

The annual mean concentration of PM2.5 was below the upper, but above the lower assessment threshold. The annual mean values ÿÿof NO2 and PM10 did not exceed the lower assessment threshold. The daily mean values ÿÿof PM10 and the hourly concentrations of NO2 were below the upper, but above the lower assessment threshold.
