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.

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 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 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 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 Ny-Ålesund. Monitoring of local air quality 2016-2017.
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 and sulphur dioxide, which indicates the power station and the harbour as possible sources. 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.

Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2018.
De målte konsentrasjonene var generelt lave for alle komponenter og under nasjonale grenseverdier for beskyttelse av menneskets helse og økosystemet.Vind fra nordlige sektorer ga de høyeste gjennomsnittskonsentrasjonene av nitrogenoksider og svoveldioksid, noe som peker på kraftstasjonen og havnen som mulige kilder. Måleresultatene for CO2 viser en årlig variasjon, med høyere konsentrasjoner om vinteren og lavere om sommeren. Kilder for de målte konsentrasjonene av CO var mest sannsynlig lokal snøskutertrafikk.

Air quality in Sandefjord, Norway. November 2021 – August 2023.
This report examines the air quality patterns in terms of particulate matter with a diameter less than 2.5 μm (PM2.5) in Sandefjord, Norway. PM2.5 was monitored through five low-cost sensors in hourly resolution from November 2021 to August 2023. The sensors’ reliability is high, with consistent PM2.5 measurements and similar variation over time. Occasional extreme PM2.5 was attributed to local contributions with higher values observed during cold months, or specific long-range transport events. Overall, Sandefjord maintained good air quality for most of the measurement period with daily PM2.5 levels below the air quality criteria. Residential heating activities (wood burning) is the most significant local source, being more pronounced during winter.

Measurement of air quality and evaluation of risk for damage to objects in three buildings belonging to the Museum of Cultural History in Oslo, were performed in the years 2010-13 as part of two EU projects: ¿TeACH¿ (Grant agreement no. 212458) (2008-2011) and ¿MEMORI¿ (Grant agreement no. 265132). The measuements were perforemed with different kinds of dust and particle collectors and with dosimetry measuring damage on sensitive materials.
