Local Environmental Conditions
The area around the heart of Calista is mostly woodland, with a good deal of built-up land and some open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Trees are an important local pollen source, given how much woodland surrounds the area. Grass pollen is significant here, and pigweed contributes weed pollen.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into mid-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.

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