Local Environmental Conditions
In Bar-le-Duc, tree pollen mainly comes from oak and hornbeam found in parks and along the Moselle. Surrounding Alsace-Lorraine cereal and vineyard land contribute substantial grass and scrub pollen, and the continental climate creates some local variation in exposure through the season.
Bar-le-Duc's pollen calendar starts in late winter, led by hazel and alder, with oak and hornbeam rising to a peak by mid-spring, before grass and cereal then carries the season into early summer, typical of this continental part of France.

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