Local Environmental Conditions
The area around the heart of Lena is mostly farmland, with some built-up land and woodland. The allergenic tree mix nearby includes birch. Grass pollen is significant here, and plantain contributes weed pollen. Field margins, fallow strips and pasture around the farmland add further grass and weed pollen. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Birch leads the season in late spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in midsummer and keep pollen in the air into late summer. Plantain brings a final peak from late spring into late summer. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.

How often is the Lena pollen forecast updated?

Does pollen in Lena 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 Lena 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 Lena, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
