Forecasting the presence of atmospheric pollens

The forecasting process includes several aspects. The scientific aspects include (i) a priori observations, like statistics of weather attributes during recent years, variation of earlier atmospheric pollen amounts, and general correlations between weather factors and pollen frequencies. (ii) The present-day observations are made closer to the flowering season, and they include e.g. the development of the present and forecasted weather, the development of the flower buds, and information obtained from other countries. The practical aspects include effective television, radio and newspaper service, necessary education and information, rapid data analysis and transfer systems, and good national and international cooperation.
