ENV08

1. Use test aerosol particles in test chambers, to develop traceable methods for the calibration of optical and aerodynamic particle size spectrometers to determine mass and number concentration, as well as size distribution. In addition, to characterise aerosol bipolar charge conditioners in mobility particle size spectrometers and based on this the pre-normative definition of their performance criteria... 2. Develop new calibration procedures for automatic pollen monitoring instruments based on fluorescent polystyrene latex and real pollen particles (at concentrations < 1 /cm3, and particle sizes of 0.5 μm up to > 20 μm, with target uncertainties of < 10 %). In addition, comparisons to reference instruments in the field will be used to characterise instrument responses to pollen.
