Local Environmental Conditions
Almost 45% of the area near this part of Denison is built-up land, with a good deal of woodland and some open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Common allergenic trees nearby include maple and oak. Grasses and weeds such as ragweed round out the local mix.
Tree pollen peaks in early spring, when the weather warms to around 15°C and maple and oak are in full flower. Grasses take over in late spring, with temperatures around 25°C, and their pollen lingers into early fall. Later, ragweed keeps weed pollen in the air from late summer into mid-fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Denison 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 Denison 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 Denison, 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. |
