Commerce City's South Platte River industrial Denver suburban setting features cottonwood, Russian olive, and elm as the main tree pollen sources, with exposure varying between the limited greener residential areas along the South Platte and the more built-up industrial and commercial corridors. The South Platte River corridor provides the most significant local green space, while the extensive industrial land use limits local vegetation considerably compared to more residential Denver suburbs.

How often is the Commerce City pollen forecast updated?

Does pollen in Commerce City 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 Commerce City 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 Commerce City, 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.
