Air quality in Ny-Ålesund. Monitoring of local air quality 2014-2015. NILU report
The concentrations of the measured components are generally low and below national limit values for the protection of human health and critical levels for the protection of vegetation.
Wind from northern sectors gave the highest average concentrations of nitrogen oxides, which indicates the power station and the harbour as possible sources. From September 2014 to February 2015, volcanic eruptions at Iceland emitted large volumes of SO2, which gave episodes of elevated concentrations in Ny-Ålesund. The measurement results for CO2 show an annual variation with higher concentrations in the winter and lower in summer. Measured concentrations of CO were most likely caused by local snowmobile traffic and long-range transport of emissions from wildfires in North America.

Air Quality in Norwegian cities. Handbook for luftkvalitet.info - administration. NILU TR
This handbook offers an introduction to the webportal admin.luftkvalitet.info developed by NILU for The Norwegian Public Roads Administration and The Climate and Pollution Agency (Klif). The modules in luftkvalitet.info - administration provides necessary tools for quality insurance and handling of air quality data in the Norwegian national measurement database.

Air quality in Norwegian cities in 2015. Evaluation report for NBV main results. NILU report
This report documents the final deliveries of the first phase of development of the Norwegian Air Quality Planning Tool, also called ¿Nasjonalt Beregningsverktøy¿ or NBV. The main purpose of NBV is to provide a common methodological and information platform for local air quality modelling applications. The system is addressed to local and regional environmental authorities, air quality experts and consulting companies. It is intended to help them meet the requirements of current air quality legislation, to support local air quality planning and facilitate air quality good practices where people live.
The report constitutes a comprehensive user guide for the NBV services available at http://www.luftkvalitet-nbv.no. It presents each of the different products developed at NBV, documents how the product has been calculated, provides recommendations on how best to use it for planning purposes and explains the main strengths and limitations of each product. The report also includes an extensive validation of the air quality information currently available at NBV.

Air quality in Hamar. Monitoring program December 2010 - June 2011. NILU OR
NILU has carried out monitoring of air quality in the center of Hamar from December 2010 till May 2011. The results have been compared to corresponding measurements at Lillehammer. The level of NO2 is lower and the level of PM10 is higher at Hamar, compared to Lillehammer. The limit value for number of days with PM10 above 50 µg/m3 is probably exceeded in the center of Hamar.

Air quality in Europe - 2018 report
The current report presents an updated overview and analysis of air quality in Europe from 2000 to 2016. It reviews the progress made towards meeting the air quality standards established in the two EU Ambient Air Quality Directives and towards the World Health Organization (WHO) air quality guidelines (AQGs). It also presents the latest findings and estimates on population and ecosystem exposure to the air pollutants with the greatest impacts and effects. The evaluation of the status of air quality is based mainly on reported ambient air measurements, in conjunction with modelling data and data on anthropogenic emissions and their evolution over time.
