Kartlegging av lokal luftkvalitet i Hønefoss. Målinger 2018-2019.
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.

Tiltaksutredning for lokal luftkvalitet i Tromsø
The air quality assessment covers mapping of the air quality in Tromsø through traffic, emission and dispersion calculations of PM10, PM2,5 and NO2 for the present situation (2016) and future scenarios (2023) with and without measures on particulate matter. Based on the calculations and in coordination with Tromsø municipality and the workgroup, a plan for improved local air quality and a management plan for periods with high concentration levels is proposed for political processing.

The aim of the study is to assess the effect of the subsidy to replace old wood stoves for new clean burning stoves, and to what extent the scheme has influenced the total particle emissions and pollution concentrations in Oslo municipality. NILU selected three methods; 1) emission and dispersion modelling for 4 different scenarios; 2) estimate the emission reduction associated with the subsidy scheme in Oslo municipality; and 3) a comparison of changes in emissions, wood consumption and emission factors over time in municipalities with and without subsidy. Modeling and assessment of the potential emission reduction associated with the subsidy scheme shows that it has a potentially significant effect on the reduction of particulate emissions and concentrations of PM2.5 and PM10. The estimates show that the subsidy scheme in Oslo municipality gives a significant reduction in average emission factor over time. However, the effect on total PM-emissions is small.
