  2. 1. Critical loads - assessment of uncertainty

    Author : Andreas Barkman; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landscape planning; regionalisation; forestry; BC Al; sensitivity analysis; risk assessment; Monte Carlo simulation; PROFILE; critical level; exceedance; Acidification; forest soil; policy; EMEP; GIS.; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. READ MORE

  4. 2. The influence of climate on ozone risk for vegetation

    Author : Jenny Klingberg; Göteborgs universitet; []
    Keywords : local climate; topography; nocturnal temperature inversions; ozone spring peak; passive diffusion sampler; AOT40; stomatal ozone flux; stomatal conductance; phytotoxic ozone dose; EMEP; MATCH; RCA3; climate change;

    Abstract : Ground-level ozone (O3) is a harmful air pollutant causing reduced crop yield and quality, reduced forest growth and negative effects on human health in large parts of the world. O3 is generally seen as a regional scale air pollution problem, but O3 concentration ([O3]) variation on a smaller geographical scale can be considerable. READ MORE

  5. 3. Carbonaceous Aerosol in Europe - out of the woods and into the blue?

    Author : Jan Robert Bergström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic aerosol; elemental carbon; chemical transport modelling; residential wood combustion; biotic stress induced emissions; source apportionment; EMEP MSC-W model;

    Abstract : Particulate matter (PM) in the atmosphere influences weather and climate and may have important health impacts. Regional scale chemical transport modelling aims to describe the composition of particulate matter, to track different sources, estimate their relative importance, and to give realistic predictions of responses to changes in emissions and atmospheric conditions.

  6. 4. Source apportionment of carbonaceous aerosol - Measurement and model evaluation

    Author : Johan Genberg; Ergonomi och aerosolteknologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Aerosol particles are found in the whole troposphere. Research regarding these particles has gained increased attention because of the effect the particles have on both health and climate. In the atmosphere, aerosol particles scatter incoming solar radiation and this has a cooling effect on the Earth’s climate. READ MORE

  7. 5. Trend Analysis and Model Comparison of Ground-Based Solar FTIR Data

    Author : Jon Angelbratt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Network for the Detection of Atmospheric Composition Change (NDACC) was initiated in the early 90s to investigate the major atmospheric problem of the day, the destruction of stratospheric ozone. About three years later solar FTIR measurements were started in Harestua, 50 km north of the Norwegian capital Oslo. READ MORE
