Maisons-Alfort's Marne and Seine river confluence green spaces 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 confluence channels airflows from multiple directions, while surrounding Île-de-France farmland contributes additional grass and tree pollen throughout the season.

Does pollen in Maisons-Alfort 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 Maisons-Alfort 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 Maisons-Alfort, 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.
