Local Environmental Conditions
Røstlandet is a small Nordland island village in Røst municipality on Norway's outermost archipelago where coastal grassland, limited birch scrub, and sea campion are the main local pollen sources. The Norwegian Sea position means extremely strong and very frequent onshore winds dominate pollen dispersal, while the subarctic oceanic climate produces one of Norway's most exposed and weather-interrupted pollen environments throughout the brief summer season.
Røstlandet's pollen calendar extends from March all the way through August, opening gently with alder and hazel starting around March, before birch peaks strongly and staying strong through June. Grass pollen extends the season through June and July. With the mix of sheltered straits and exposed coast around Røstlandet, the local climate gives this area its own distinct rhythm within the wider Norwegian season.

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