Working Group 1 

Chair: Dr. Arnold van Vliet

Pollen production and release:

WP1 will be dedicated to pollen production and release and their quantitative descriptions. It will include analysis of observational (both in-situ and remote-sensing) and modeling (with various types of models) information for revealing key characteristics of these processes.

Specific objectives:

• to review and harmonize the existing direct and indirect information on distributions of key pollen species from local to European scales
• to review and evaluate against available observations the existing and developing models of pollen emissions over Europe, their strengths and weaknesses;
• to utilize in a comprehensive manner the semi-qualitative phenological descriptions of pollen production and release, as well as their dependence on short- and long-term external forcing
• to analyze the strengths and limitations of satellite observations and possibility of their nearreal-time assimilation for pollen analysis and forecasting
