Saint-Maur-des-Fossés' Marne peninsula green spaces and the Marne River corridor feature plane, oak, and linden as the main tree pollen sources, with exposure varying between these areas and the densely built suburban landscape. As part of the greater Paris metropolitan area, the river peninsula setting channels airflows and the riverside meadows contribute locally significant grass pollen, while surrounding Île-de-France farmland adds additional exposure.

Does pollen in Saint-Maur-des-Fossés 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 Saint-Maur-des-Fossés 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 Saint-Maur-des-Fossés, 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.
