Barra Mansa occupies the Rio de Janeiro Paraíba do Sul valley industrial region where the river bends through the Serra, where native Atlantic Forest remnants, eucalyptus, and the Paraíba do Sul River corridor vegetation are the main pollen sources. The tropical climate supports year-round pollen production, while the wet summer months bring the most frequent rainfall interruptions and the enclosed valley concentrates pollen under calm conditions throughout.

Does pollen in Barra Mansa 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 Barra Mansa 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 Barra Mansa, 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.
