Local Environmental Conditions
Around 43% of the area near the center of Calvert is woodland, with a good deal of open grassland and some built-up land. Lawns and planted trees in a nearby park add to local grass and tree pollen. With this much woodland around, trees are an important local pollen source. Grass pollen adds noticeably to the overall load.
Trees are the first to release pollen, with a peak around early spring. Grasses are next, reaching their height around late spring and tailing off by late summer. Later, weeds flowering on open and disturbed ground keep some pollen in the air from early summer into early fall. Here, temperatures range from around 10°C in the coldest month to around 30°C in the warmest.

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