Sterling sits on the South Platte River valley on Colorado's northeast plains, where the dominant vegetation is a mix of cottonwood along the river, shortgrass prairie, and farmland crops, shaping the local pollen profile across the seasons. None of this is unusual for a town with Sterling's particular mix of terrain and plant life. Residents who spend time outdoors around Sterling typically notice the shift as each season turns over.

Does pollen in Sterling 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 Sterling 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 Sterling, 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.
