Local Environmental Conditions
Woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen; this sits within the neighborhood. Nearby, in the surrounding area, green space with maintained lawn and planted trees, both contributing to grass and ragweed counts. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
Woodland oak and birch pick up the pace next, through mid-to-late spring, climbing steadily through spring to a peak in April or May. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed takes over as the dominant allergen from mid-August through October. Neighboring parts of the county typically see this same sequence with only minor timing shifts.

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