Local Environmental Conditions
Bismo is a small Innlandet village in Skjåk municipality in the Ottadalen valley where birch, hazel, and valley farmland vegetation are the main local pollen sources. The enclosed Ottadalen valley concentrates pollen under calm conditions, while the very dry inland continental climate means minimal rainfall interruptions and birch peaks through April and May before grass from surrounding mountain farmland contributes through June and July throughout this high Gudbrandsdalen side valley community.
Bismo's pollen calendar plays out between March and August, opening with alder and hazel as early as March, with birch reaching its clearest peak through to May. Grass pollen extends the season into June and July. With the surrounding forestry land and farmland near Bismo, the local climate leaves this area with a noticeably local twist on the general pattern.

How often is the Bismo pollen forecast updated?

Does pollen in Bismo 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 Bismo 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 Bismo, 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.

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. |
