Local Environmental Conditions
Scrubland and open grassland share the area around the heart of Casa Nova, plus some built-up land. With the Francisco River nearby, riverside vegetation along its banks contributes to the local mix. Around here, open grassland adds grass and weed pollen; scrubland contributes pollen from shrubs, grasses and herbs. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
With warm weather all year, between about 25°C and 30°C, pollen is present in most months rather than in one short season. The drier stretch around July to September usually brings the most pollen. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. Grasses flower again and again through the year and are the most constant source.

How often is the Casa Nova pollen forecast updated?

Does pollen in Casa Nova 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 Casa Nova 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 Casa Nova, 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. |
