Short summary
Atmospheric mineral dust influences Earth's radiative budget, has adverse health effects, and affects regulatory PM10 concentrations. We present a highly time resolved online technique for quantification of mineral dust concentration in ambient air. The technique uses a virtual impactor to concentrate coarse particles, where absorption is then measured using a filter photometer. The method was tested in the field at a regional background site on Cyprus.
