Birch pollen is the most common aeroallergen. About 20% of popula.on in Europe suffers allergenic reac.ons from pollen, and this number is constantly increasing. Therefore, people suffered to allergenic diseases (such as rhini.s) need to know: where and when there will be high pollen concentra.on. For this reason, a module for forecas.ng of birch pollen concentra.ons has been developed as a part of EnviroHIRLAM modeling system, and used in opera.onal mode for several years. The latest version of the model presented here includes growing degree hour parameteriza.on for start of flowering season, birch forest spa.al distribu.on, birch pollen emissions from local sources, dry and wet deposi.on processes for pollen par.cles in the atmosphere.

The model includes chemical, aerosol and pollen species. Schema.c descrip.on of birch pollen forecas.ng system is shown in figure 3. Birch forest habitat maps (fig. 4) have been derived for both modelling domains (fig. 1,2). The maps are result of combining and processing of three GIS databases: Global Land Cover (GLC) (landcover.usgs.gov/glcc/), European Forest Ins.tute (EFI) (Päivinen et al. 2001), and Tree Species Inventory (TSI) (Skjøth et al. 2008).
