This annual report for 2022 summarizes the activities and results of the greenhouse gas monitoring at the Zeppelin Observatory, situated on Svalbard, during the period 2001-2022, and the greenhouse gas monitoring and aerosol observations from Birkenes for 2009-2022.

The potential re-design of the current deposition monitoring network in Poland was assessed by hierarchical clustering analysis. This statistical method determines the inherent or natural groupings of datasets, and/or to provide a summarization of data into groups using different metrics to assess the (di)similarity. The metrics are based on the correlation, to assess the temporal similarity, the Euclidean distance, to assess the magnitude similarity, and the combination of both. This method was used to assess the areas with similar deposition patters across the country based on measurement and model data for acidic compounds and heavy metals. The analysis clearly identified stations potentially redundant or measuring unique deposition patters and regions that represent the potential location of a single station.

There is considerable interest in identifying chemicals which have the potential to undergo long-range environmental transport (LRTP), accumulate in remote regions, and represent a possible risk to environmental and human health. In this report, we have screened a list of 1,000 organic chemicals, as well as selected brominated dioxins and furans (PBDD/Fs), for their potential to be dispersed, transferred to, and accumulated in remote regions. This screening was carried out applying a new set of LRTP metrics, collectively referred to as the emissions fractions approach (EFA), as implemented in a modified version of the OECD POV and LRTP (long-range transport potential) Screening Tool (The Tool).

Måling av maursyre og eddiksyre i to oppbevaringsbokser ved Munchmuseet i Oslo
Målinger av maursyre (HCOOH), eddiksyre (CH3COOH) og flyktige organiske forbindelser (VOC) ble gjort i to oppbevaringsbokser ved Munchmuseet i Oslo. Noe forhøyede konsentrasjoner av maursyre, eddiksyre og totale flyktige organiske forbindelser (TVOC) ble målt i boksene, men konsentrasjonene er like fullt lave sammenlignet med vurderte risikonivåer for kulturav-materialer.

Skogens helsetilstand i Norge. Resultater fra skogskadeovervåkingen i 2022
Skogens helsetilstand påvirkes i stor grad av klima og værforhold, enten direkte ved tørke, frost og vind, eller indirekte ved at klimaet påvirker omfanget av soppsykdommer og insektangrep. Klimaendringene og den forventede økningen i klimarelaterte skogskader gir store utfordringer for forvaltningen av framtidas skogressurser. Det samme gjør invaderende skadegjørere, både allerede etablerte arter og nye som kan komme til Norge i nær framtid. I denne rapporten presenteres resultater fra skogskadeovervåkingen i Norge i 2022 og trender over tid for følgende temaer:
(i) Landsrepresentativ skogovervåking;
(ii) Intensiv skogovervåking;
(iii) Overvåking av bjørkemålere i Troms og Finnmark;
(iv) Barkbilleovervåkingen;
(v) Furuvednematode;
(vi) Askeskuddsyke;
(vii) Andre spesielle skogskader i 2022.

Environmental Contaminants in an Urban Fjord, 2022
This report presents data from the second year of a new 5-year period of the Urban Fjord programme. The programme started in 2013 and has since been altered/advanced. In 2022 the programme covers sampling and analyses of sediment, polychaetes, krill, shrimps, blue mussels, herring, cod, eider, and herring gull from the Inner Oslofjord. In addition, samples of Harbour seals from the Outer Oslofjord are analysed. A total of ~300 single compounds/isomers were analysed, and frequent detection was found of certain PFAS compounds (such as PFOS) in most matrices, certain QACs in sediment, MCCPs in most matrices (also SCCPs in birds and seals, as well as LCCPs in seals), D5 (siloxane) in all matrices, certain PBDEs (such as BDE 100) in most matrices, PCBs in all matrices, BCPS (phenolic) in seals and certain metals in all matrices. Biomagnification was observed for 28 PCB congeners and 6 PBDEs (lipid wt. basis). Furthermore, biomagnification was observed for 5 PFAS compounds, as well as for the metals As, Ag and Hg (wet wt. basis).

This paper examines the creation of fine resolution maps at 100 m x 100 m resolution using statistical downscaling for the area of Prague, as a case study. This Czech city was selected due to the fine resolution proxy data available for this city. The reference downscaling methodology used is the linear regression and the interpolation of its residuals by the area-to-point kriging. Next to this, several other methods of statistical downscaling have been also executed. The results of different downscaling methods have been compared mutually and against the data from the monitoring stations of Prague, separately for urban background and traffic areas.
The downscaled maps in 100 m x 100 m resolution have been constructed for the area of Prague for three pollutants, namely for NO2, PM10 and PM2.5. Several methods of the statistical downscaling have been compared mutually and against the data from the monitoring stations. In general, the best results are given by the linear regression and the interpolation of its residuals, either by the area-to-point kriging or the bilinear interpolation. In the maps, one can see overall realistic spatial patterns, the main roads in Prague are visible through higher air pollution levels. This is distinct especially for NO2, while for PM10 and PM2.5 the differences between road increments and urban background are smaller as would be expected. The results of the case study for Prague have proven the usefulness of the statistical downscaling for the air quality mapping, especially for NO2. In addition, the population exposure estimates based on the downscaled mapping results have been also calculated.

Environmental pollutants in the terrestrial and urban environment 2022
Samples of soil, earthworm, fieldfare egg, brown rat liver, spanish slug, house dust and cat liver from the urban terrestrial environment in the Oslo area were analysed for several different groups of environmental pollutants. Biota-soil accumulation was calculated from soil to earthworm from the same location, and biomagnification-potential was estimated based on detected data for relevant predator-prey pairs from the same location.

Establishment of an early warning system (EWS) for the identification of new and existing potentially hazardous substances is a key component of PARC. An EWS includes early warning monitoring toolboxes to identify chemical hazards in a broad range of biotic and abiotic matrices and products with a special focus on aqueous environment that may be associated with an unacceptable health risk. Effect-based monitoring (EBM) and effect-directed analysis (EDA) are identified as key toolboxes for prioritizing chemical hazards in various matrices including water, soil, sediment, sludge, air, dust, aquatic and terrestrial biota, human samples, products like food contact materials, and food. This report gives an overview of i) sampling strategies, ii) sample preparation methods for bioassays and chemical analysis, iii) EBM using bioassays, iv) chemical analytical methods including target, suspect and nontarget screening, v) EDA and iceberg modelling, and vi) future perspectives and needs for an EWS.

Satellite remote sensing of Arctic fires - a literature and data review
The main aim of this report is to prepare for the proposed SGA #17 of the Caroline Herschel Framework Partnership Agreement on Copernicus User Uptake Work Programme 2020 named “Arctic peat- and forest-fire information system”. First, we summarize the scientific background of wildfires in the Arctic and the Northern boreal zone and describe observations of long-range transport of forest fire pollution. This is followed by an overview of satellite data and resources available for fire monitoring in these regions. This covers the fire ECVs, as well as smoke plume tracers. Furthermore, we list CAMS and CEMS resources, i.e., GWIS, EFFIS (including the latest country report for Norway), and GFAS, as well as other fire emission inventories. Knowledge gaps and limitations of satellite remote sen.sing, future missions, Norwegian user uptake and user groups are described.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual Report 2022.
This report summarizes the results from the Norwegian monitoring programme on stratospheric ozone and UV radiation measurements. The ozone layer has been measured at three locations since 1979: In Oslo/Kjeller, Tromsø/Andøya and Ny-Ålesund. The UV-measurements started in 1995. The results show that there was a significant decrease in stratospheric ozone above Norway between 1979 and 1997. After that, the ozone layer stabilized at a level ~2% below pre-1980 level. The year 2022 was characterized by annual average total ozone values slightly below “normal”.
