The overall goal of this project is to investigate birch pollen production and emission by combining experimental and modeling work in order to quantify the released pollen in relation to turbulence characteristics and micrometeorological parameters around a pollen source. Emission parameters are the least known part of the new generation of pollen forecast systems, which are based on transport and dispersion models.

A second focus is the development and validation of a pollen emission scheme based on the results from the present field campaign. Furthermore, this scheme will be tested using state-of-the-art atmospheric transport models which are optimized by the measured exchange conditions. The models are the LM-ART and/or other models used by COST partners.
