Air quality in Ny-Ålesund. Monitoring of local air quality 2014-2015.

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

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

NILU - Norsk institutt for luftforskning har på oppdrag fra Ringerike kommune gjennomført kartlegging av lokal luftkvalitet i Hønefoss. Måleprogrammet startet juni 2018 og ble avsluttet i mai 2019. Målingene ble gjennomført for å framskaffe kunnskapsgrunnlag for ny byplan i Hønefoss. Måleprogrammet inneholdt måling av svevestøv og nitrogendioksid samt meteorologiske parametre som temperatur, trykk, relativ fuktighet og vind. Årsmiddelkonsentrasjonen av PM2,5 lå under øvre, men over nedre vurderingsterskel. Årsmiddelverdiene av NO2 og PM10 lå ikke over nedre vurderingsterskel. Døgnmiddelverdier av PM10 og timemiddelkonsentrasjon av NO2 lå under øvre, men over nedre vurderingsterskel

Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2018.

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 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.

Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2019 and 2020.

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 sulfur dioxide, which indicates the power station and the harbour as possible sources. We also see single episodes of long-range transport of sulfur dioxide

Effects of rocket launches in Ny-Ålesund, 2018 - 2019. Observations of snow and air samples.

The report summarizes the results from additional snow sampling and regular monitoring activities in connection to the rocket launch in Ny-Ålesund 7 Dec 2018, 26 Nov 2019 and 10 Dec 2019 to document possible impacts on environment and on the monitoring activities in Ny-Ålesund. An enhanced deposition of aluminium (Al) and iron (Fe) on the local environment due to the rocket launch is observed

Atmospheric composition in the European Arctic and 30 years of the Zeppelin Observatory, Ny-Ålesund

The Zeppelin Observatory (78.90°;N, 11.88°;E) is located on Zeppelin Mountain at 472 m a.s.l. on Spitsbergen, the largest island of the Svalbard archipelago. Established in 1989, the observatory is part of Ny-Ålesund Research Station and an important atmospheric measurement site, one of only a few in the high Arctic, and a part of several European and global monitoring programmes and research infrastructures, notably the European Monitoring and Evaluation Programme (EMEP); the Arctic Monitoring and Assessment Programme (AMAP); the Global Atmosphere Watch (GAW); the Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS); the Advanced Global Atmospheric Gases Experiment (AGAGE) network; and the Integrated Carbon Observation System (ICOS). The observatory is jointly operated by the Norwegian Polar Institute (NPI), Stockholm University, and the Norwegian Institute for Air Research (NILU). Here we detail the establishment of the Zeppelin Observatory including historical measurements of atmospheric composition in the European Arctic leading to its construction. We present a history of the measurements at the observatory and review the current state of the European Arctic atmosphere, including results from trends in greenhouse gases, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), other traces gases, persistent organic pollutants (POPs) and heavy metals, aerosols and Arctic haze, and atmospheric transport phenomena, and provide an outline of future research directions
