Local Environmental Conditions
Located on the Ligurian Riviera coast, Imperia in Liguria draws most of its tree pollen from pine and oak, while grass contributes further exposure as the season progresses. Green spaces close to the built-up centre see noticeably different totals than the more open outskirts nearby, where surrounding farmland and woodland add their own seasonal contribution to the mix.
Spring in Imperia brings the sharpest pollen exposure, led by pine and oak after an early olive and plane start; grass extends the season into summer, with the overall period running January through August. a typically dry summer means late-season exposure stays low.

How often is the Imperia pollen forecast updated?
The Imperia pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Imperia 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 Imperia 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 Imperia, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
