Pollen flight forecasting in Germany and in Europe.

Every tenth person in Central Europe is a pollinosis patient. The time of ripening and release of pollen, as well as pollen flight, all depend on the weather. Because each year is different from every other, mean values from pollen calendars do not provide any practical help for allergy-sufferers. For this reason, in many European countries, measuring networks have been established during the last 10 years as a basis for forecasting the prevalence of airborne pollen for the following 2-3 days, in connection with the weather forecast. Cooperation and communication also exist on a European level, and a European Pollen Database had been established.
