The 5-years assessment of air quality, the Norwegian experience. NILU OR

Guerreiro, C.; Bøhler, T.

This report describes the Norwegian experience and "best practices" regarding the approach to classify zones and agglomerations in relation to the upper and lower assessment thresholds, as required in Article 5 of Directive 2008/50/ EC and Article 4 of Directive 2004/107/ EC. It is based on the recent air quality assessments done in Norway and gives a brief overview over the available relevant information and methods NILU would consider in such an assessment. A short description of Norway's assessment zones and agglomerations and monitoring networks is also provided.

The active layer soils of Greenlandic permafrost areas can function as important sinks for volatile organic compounds

Permafrost is a considerable carbon reservoir harboring up to 1700 petagrams of carbon accumulated over millennia, which can be mobilized as permafrost thaws under global warming. Recent studies have highlighted that a fraction of this carbon can be transformed to atmospheric volatile organic compounds, which can affect the atmospheric oxidizing capacity and contribute to the formation of secondary organic aerosols. In this study, active layer soils from the seasonally unfrozen layer above the permafrost were collected from two distinct locations of the Greenlandic permafrost and incubated to explore their roles in the soil-atmosphere exchange of volatile organic compounds. Results show that these soils can actively function as sinks of these compounds, despite their different physiochemical properties. Upper active layer possessed relatively higher uptake capacities; factors including soil moisture, organic matter, and microbial biomass carbon were identified as the main factors correlating with the uptake rates. Additionally, uptake coefficients for several compounds were calculated for their potential use in future model development. Correlation analysis and the varying coefficients indicate that the sink was likely biotic. The development of a deeper active layer under climate change may enhance the sink capacity and reduce the net emissions of volatile organic compounds from permafrost thaw.
