Local Environmental Conditions
Mo i Rana is a small Nordland industrial town in Rana municipality at the head of the Ranfjord where birch, alder, and fjord valley woodland are the main local pollen sources. The enclosed Ranfjord head valley concentrates pollen under calm conditions, while the subarctic Atlantic climate provides regular rainfall interruptions and birch peaks through May before grass from surrounding Rana farmland contributes through June and July throughout this Nordland steel industry town.
Pollen in Mo i Rana covers the period from March through August, opening with alder and hazel in March, then birch dominates with a pronounced peak through to June. Mo i Rana then sees grass pollen continue into June and July. With the open Norwegian Sea exposure just offshore from Mo i Rana, the local climate adds its own local variation on top of the general national pattern.

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