Local Environmental Conditions
Bjørkelangen is a small Akershus inland village in Aurskog-Høland municipality where birch, hazel, and boreal woodland edge vegetation are the main local pollen sources. The inland Østlandet setting means a more continental climate than western Norway with fewer rainfall interruptions, while birch peaks through April and May before grass from surrounding farmland contributes through June and July and mugwort extends exposure into September.
Pollen in Bjørkelangen covers the period from February through August, kicking off with alder and hazel from about February, with birch reaching its clearest peak continuing right through May. Grass takes over from there through the June-July stretch. With the combination of city parkland and nearby farmland around Bjørkelangen, the local climate means the timing can vary from what neighbouring districts experience.

How often is the Bjørkelangen pollen forecast updated?

Does pollen in Bjørkelangen 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 Bjørkelangen 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 Bjørkelangen, 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. |
