Abstract: | Geographical and temporal variations in the start dates of grass pollen seasons are described for selected sites of the European
Pollen Information Service. Daily average grass pollen counts are derived from Network sites in Finland, the Netherlands,
Denmark, United Kingdom, Austria, Italy and Spain, giving a broad longitudinal transect over Western Europe. The study is
part of a larger project that also examines annual and regional variations in the severity, timing of the peak and duration
of the grass pollen seasons. For several sites, data are available for over twenty years enabling long term trends to be discerned.
The analyses show notable contrasts in the progression of the seasons annually with differing lag times occurring between
southern and northern sites in various years depending on the weather conditions. The patterns identified provide some insight
into geographical differences and temporal trends in the incidence of pollinosis. The paper discusses the main difficulties
involved in this type of analysis and notes possibilities for using data from the European Pollen Information service to construct
pan European predictive models for pollen seasons.
