Local Environmental Conditions
Mebonden is a small Trøndelag village in Selbu municipality in the Selbu valley where birch, alder, and valley farmland vegetation are the main local pollen sources. The Selbu valley concentrates pollen under calm conditions, while the Atlantic-influenced but inland Trøndelag climate produces a well-defined seasonal progression with birch peaking through April and May before grass contributes through June and July throughout this Selbu lake community.
In Mebonden, the pollen season typically lasts from March through August, starting quietly with alder and hazel picking up from March, then birch dominates with a pronounced peak through May. Mebonden then sees grass pollen continue and holds through June and July. With the wide river valleys draining toward the Trondheimsfjord, the local climate gives the season here a somewhat different character than nearby districts.

How often is the Mebonden pollen forecast updated?
The Mebonden pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Mebonden 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 Mebonden 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 Mebonden, 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. |
