Spatial distribution of residential wood combustion emissions in the Nordic countries: How well national inventories represent local emissions?
(Peer reviewed; Journal article, 2021)Residential wood combustion (RWC) is a major source of air pollutants in the Nordic and many other countries. The emissions of the pollutants have been estimated with inventories on several scopes, e.g. local and national. ... -
Spatial inter-comparison of top-down emission inventories in European urban areas
(Journal article; Peer reviewed, 2018) -
Spatial patterns and temporal trends of heavy metal concentrations in moss and surface soil specimens collected in Norway between 1990 and 2010

Spatial trends of chlorinated paraffins and dechloranes in air and soil in a tropical urban, suburban, and rural environment
(Peer reviewed; Journal article, 2022)There are large knowledge gaps concerning environmental levels and fate of many organic pollutants, particularly for chemicals of emerging concern in tropical regions of the Global South. In this study, we investigated the ... -
Spatial variability and temporal changes of POPs in European background air
(Peer reviewed; Journal article, 2023)Concentration data on POPs in air is necessary to assess the effectiveness of international regulations aiming to reduce the emissions of persistent organic pollutants (POPs) into the environment. POPs in European background ... -
Spatial variability of POPs in European background air
(Journal article; Peer reviewed, 2011)Passive air samplers (PAS) were deployed at 86 European background sites during summer 2006 in order (i) to gain further insight into spatial patterns of persistent organic pollutants (POPs) in European background air and, ... -
Spatio-temporal variability of the polar middle atmosphere. Insights from over 30 years of research satellite observations.
(NILU TR;01/2012, Research report, 2012)We discuss the insights that research satellite observations from the last 30 years have provided on the spatio-temporal variability of the polar middle atmosphere. Starting from the time of the NASA LIMS (Limb Infrared ... -
Spatiotemporal Analysis of Perfluoroalkyl Substances in White-Tailed Eagle (Haliaeetus albicilla) Nestlings from Northern Norway-A Ten-Year Study
(Peer reviewed; Journal article, 2020)The white-tailed eagle (Haliaeetus albicilla) in Scandinavia has suffered from impaired reproduction due to high exposure to industrial pollution between the 1960s and 1980s. While population numbers are rising again, new ... -
Spatiotemporal Patterns in Data Availability of the Sentinel-5P NO2 Product over Urban Areas in Norway
(Peer reviewed; Journal article, 2021)Due to its comparatively high spatial resolution and its daily repeat frequency, the tropospheric nitrogen dioxide product provided by the TROPOspheric Monitoring Instrument (TROPOMI) onboard the Sentinel-5 Precursor ... -
SPECIAL MEASUREMENTS AT NY ÅLESUND: PHYSICAL AND CHEMICAL PROPERTIES OF THE ARCTIC AEROSOL.
(NILU OR;65/85, Research report, 1985)Physical and chemical properties of the arctic aerosol at Ny Ålesund, Spitsbergen, have been studied during the arctic winter and summer seasons. Size-differentiated chemical composition of aerosols has been used to assess ... -
