Turbulent transport of aerosol particles

Direct measurement of the turbulent biosphere-atmosphere exchange of aerosol particles, and the particulate input of trace compounds into ecosystems is still a great challenge. We employ micrometeorological techniques including eddy covariance and relaxed eddy accumulation to quantify turbulent aerosol fluxes in the boundary layer.

 

 

Particle formation in the atmosphere

Understanding new particle formation in the atmosphere (secondary particle formation) is a prerequisite to quantify the contribution of aerosol particles to nutrient and pollutant budgets, and to estimate the regional radiative forcing of the atmospheric aerosol. We study particle nucleation events and particle growth rates in various ecosystems using different experimental methods.

 

 

Aerosol mass spectrometry

Aerosol mass spectrometry has developed rapidly over the last few years. We have used laser desorption ionization (LDI) mass spectrometry and thermal desorption chemical ionization mass spectrometry (TDCIMS) to study the chemical composition of submicron particles. Currently, we develop a portable thermal desorption time-of-flight mass spectrometer to analyze freshly nucleated aerosol particles.
