Abstract [en]

A unique long-term (1983-2013) dataset of sulfur and nitrogen deposition has been compiled for Sweden as well as the Baltic Sea and surrounding countries, based on quality controlled measurements and modelled fields, fused though advanced methods capturing spatial and temporal variations. The data set can be used for describing trends in deposition to various relevant surface types.Our reanalysis compares well to observations, but we have identified differences in dry deposition to coniferous forest. This calls for more in-depth studies of the dry deposition and improvements to the respective methods.We recommend more advanced methods of describing spatial variation than averaging or spatial interpolation of observed deposition.We estimate a significant decrease from the 1980s until today for both sulfur and nitrogen deposition (by ca. 80% and 30% respectively).Critical loads for coniferous and deciduous forests, mountain vegetation and wetlands have been surpassed mainly in the southwest Sweden, but also in southeast Sweden and the southern parts of Scandes Mountains. The situation is improving, but exceedances do still occur also in larger regions.

Abstract [sv]

Ett unikt långt dataset (1983-2013) för svavel- och kvävedeposition har skapats för Sverige samt Östersjön och omgivande länder. Det baseras på kvalitetsgranskade mätningar och modellfält, kombinerade genom avancerade metoder för att fånga spatiala och temporala variationer. Datasetet kan användas för att beskriva trender i deposition till olika relevanta marktyper.Återanalysen stämmer väl överens med mätningar, men vi har identifierat skillnader i torrdeposition till barrskog. Detta visar på behov av djupare studier och metodikförbättringar för bestämning av torrdeposition.Vi rekommenderar mer avancerade metoder för att beskriva spatial variation än genom medelvärdesbildning eller spatial interpolering av uppmätt deposition.Vi finner en markant minskning från 1980-talet fram till idag för både svavel- och kvävedeposition (med cirka 80 % respektive 30 %).Kritiska belastningar till både barr- och lövskog, fjällmarker och våtmarker har överskridits framförallt i sydvästra Sverige, men också i sydöstra Sverige och södra fjällen. Situationen förbättras men överskridanden sker fortfarande även över större områden.

Abstract [en]

Ozone, PM10 and PM2.5 concentrations over Paris, France and Stockholm, Sweden were modelled at 4 and 1 km horizontal resolutions respectively for the present and 2050 periods employing decade-long simulations. We account for large-scale global climate change (RCP-4.5) and fine-resolution bottom-up emission projections developed by local experts and quantify their impact on future pollutant concentrations. Moreover, we identify biases related to the implementation of regional-scale emission projections by comparing modelled pollutant concentrations between the fine-and coarse-scale simulations over the study areas. We show that over urban areas with major regional contribution (e.g. the city of Stockholm) the bias related to coarse-scale projections may be significant and lead to policy misclassification. Our results stress the need to better understand the mechanism of bias propagation across the modelling scales in order to design more successful local-scale strategies. We find that the impact of climate change is spatially homogeneous in both regions, implying strong regional influence. The climate benefit for ozone (daily mean and maximum) is up to 5% for Paris and 2% for Stockholm city. The climate benefit on PM2.5 and PM10 in Paris is between 5 and 10 %, while for Stockholm we estimate mixed trends of up to 3% depending on season and size class. In Stockholm, emission mitigation leads to concentration reductions up to 15% for daily mean and maximum ozone and 20% for PM. Through a sensitivity analysis we show that this response is entirely due to changes in emissions at the regional scale. On the contrary, over the city of Paris (VOC-limited photochemical regime), local mitigation of NO x emissions increases future ozone concentrations due to ozone titration inhibition. This competing trend between the respective roles of emission and climate change, results in an increase in 2050 daily mean ozone by 2.5% in Paris. Climate and not emission change appears to be the most influential factor for maximum ozone concentration over the city of Paris, which may be particularly interesting from a health impact perspective.
