How to connect?

Centreville's Northern Virginia suburban setting features oak, tulip poplar, and maple as the main tree pollen sources, with exposure varying between the wooded Bull Run Regional Park corridor and the more built-up residential and commercial areas. Bull Run Mountain and the Bull Run corridor are particularly significant local sources, while the Occoquan watershed woodland creates distinct pollen gradients between the forested eastern fringe and the more developed western areas.

How often is the Centreville pollen forecast updated?

Does pollen in Centreville 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 Centreville 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 Centreville, 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.
