Stolberg's parks and the Vicht River corridor feature oak, birch, and beech as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding North Rhine-Westphalia farmland and the Eifel woodland foothills contribute substantial tree and grass pollen, while the valley setting channels airflows and concentrates pollen across the city under prevailing westerly winds.

Does pollen in Stolberg come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Stolberg based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Stolberg, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
