Local Environmental Conditions
In Falun, spruce, birch, and oak growing in parks and green corridors account for most of the tree pollen exposure. Because open farmland sits close to Lake Runn and the historic mining valley, grass and crop pollen move freely across the area. Whether someone lives near a park or in the built-up centre of Falun makes more difference to pollen exposure than mining heritage and light industry.
Falun's pollen season runs from February through August, opening with alder from February before birch peaks strongly through May. Grass pollen picks up the baton from birch, running through most of June and July. Air moving across Lake Runn and the historic mining valley periodically clears or concentrates pollen depending on which way the wind is blowing. Late-season pollen owes more to the region's spruce cover and farmland than to any urban source.

How often is the Falun pollen forecast updated?
The Falun pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Falun 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 Falun 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 Falun, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
