Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
Sammanfattning : 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.

Sammanfattning : 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. LÄS MER
Sammanfattning : 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. LÄS MER
