Characterisation of light-absorbing atmospheric particles in the Brussels sub-urban atmosphere

Abstract:
The particle composition is important for air quality studies in the urban atmosphere. In particular, particles smaller than 1 μm are increasingly in the focus with respect to human health because of they are inhalable deeply into the human lung. A relevant part of such (ultra-)fine particles are light-absorbing particles. Important sources for such particles in the cities and residential areas are emissions from traffic (mainly soot), but also emissions from wood-burning stoves in private households. The relative contributions of these sources to the atmospheric particle load are important to know in order to be able to reduce hazardous emissions by specific measures.

The Royal Meteorological Institute of Belgium (RMI) gathers ambient aerosol data in Brussels with a 7-wavelengths aethalometer (mass concentration and absorption coefficient of light-absorbing aerosol). The measurement site is located in the sub-urban, rather residential southern part of Brussels and measurements are representative for the urban background. At the same site, the boundary layer height and atmospheric stability parameter are derived from a co-located ceilometer and eddy-covariance system. ... mehr
