Working Group 2

Chair: Dr. Heidrun Behrendt

Pollen distribution in the atmosphere:

WP2 will concentrate on pollen atmospheric dispersion at various scales, its transport and removal mechanisms, physical and chemical transformations and inter-actions with other atmospheric constituents

Specific objectives:

• To review the existing models of pollen dispersion at various spatial and temporal scales
• To analyse the physical and chemical characteristics of pollen grains and to suggest a coherent descriptions of their atmospheric dispersion, transformation and deposition
• To assess existing evidence of pollen inter-action with atmospheric pollutants and to suggest the means of quantitative description and evaluation of such processes
