Local Environmental Conditions
This site in Romoland sits among a blend of open grassland and built-up land, plus some farmland. The damp ground beside a stream or river nearby supports trees, shrubs and reeds, adding to local pollen. Grass pollen is significant here, and pigweed contributes weed pollen. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Then come the grasses, strongest in late spring and fading by early fall. The season closes with pigweed from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

How often is the Romoland pollen forecast updated?

Does pollen in Romoland 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 Romoland 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 Romoland, 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. |
