The literature on atmospheric particulate maffer (PM), or atmospheric aerosol, has increased enormously over the last 2 decades and amounts now to some 1500—2000 papers per year in the refereed literature. This is in part due to the enormous advances in measurement technologies, which have allowed for an increasingly accurate understanding of...

Online coupled mesoscale meteorology atmospheric chemistry models have undergone a rapid evolution in recent years. Although mainly developed by the air quality modelling community, these models are also of interest for numerical weather prediction and regional climate modelling as they can consider not only the effects of meteorology on air...

Many of the next generation of global climate models will include aerosol schemes which explicitly simulate the microphysical processes that determine the particle size distribution. These models enable aerosol optical properties and cloud condensation nuclei (CCN) concentrations to be determined by fundamental aerosol processes, which should...

This paper presents the aerosol budget over Europe in 2006 calculated with the global transport model TM5 coupled to the size-resolved aerosol module M7. Comparison with ground observations indicates that the model reproduces the observed concentrations quite well with an expected slight underestimation of PM10 due to missing emissions (e.g....

Aerosols have a large effect on climate and weather. They modulate the surface irradiance in clear sky conditions, but also modify the radiative properties of clouds. To assess the consequences of reduced surface irradiation due to aerosols for weather forecasting and climate, data on aerosol radiative effects and their spatial and temporal...

The atmospheric chemistry and deposition model has been applied for calculation of nitrogen and sulphur depositions to the entire North Sea area for the year 1999. The total atmospheric nitrogen and sulphur depositions to the North Sea area were determined to 709 kton (kt) N and 551 kt S, respectively. Since the North Sea area was calculated to...

Terrestrial inputs of nitrogen are often dominated by riverine transport, especially in the winter (Sanders et al., 1997). However, the atmospheric contribution to the total land based nitrogen input has been reported to be on the order of 30 % for the total North Sea area (North Sea Task Force, 1993). The atmospheric nitrogen load is directly...
