Pollen Dispersal Calendar of the German Weather Service

More than 12% of the population are allergic  to pollen with tendency to rise. The German Weather Service creates forecasts in cooperation with the "German Pollen Information Service Foundation" about the seven most important allergological pollen- about 95% of the person that are allergic to pollen suffer from these kinds of pollen -: hazel, alder, birch, sweet grass, rye, mugwort and  ambrosia. This dispersal calendar is meaningful because the beginning of the blossom of the botanical in Central Europe can  alternate up to six weeks caused by the weather. Moreover the concentration of the redundant pollen and their dispersal depends on the current weather what effects analysis of the measured data as well as the forecast of the expected dispersal of pollen.The specific prophylaxis of allergic person could be highly improved with the help of  a daily updated pollen forecast.

Basis for the Pollen Dispersal Calendar is the concentration of pollen measured and analyzed in several clinics of  local short-term and long-term wetaher forecasts of the German Weather Service as well as the German Pollen Information Service Foundation , that are relinqushed to the medical meteorology on constractual basis for the forecast. As a support for the discovery of the beginning of blossom of the allergenic botanics, the phenological data of the German Weather Service are extracted in the context of agrarian meteorological data recording.
