Des Moines' Water Works Park air quality benefits from the 1,532-acre Water Works Park's exceptional scale providing outstanding natural filtration along the Raccoon River. Vehicle traffic on Fleur Drive contributes modest local sources, while the extraordinary park scale — one of the largest municipal parks in the US — and the riparian woodland generally maintain Water Works Park among Des Moines' cleanest major public spaces throughout most of the year.

When is air pollution at its worst in Water Works Park?

Water Works Park experiences the same seasonal air quality swings as the rest of Des Moines. Typically, the calmest air usually arrives in winter, between planting and harvest dust events, while both spring planting and autumn harvest bring short bursts of elevated dust and smoke. Farm-heavy surrounding land is the main source of the seasonal dust spikes.

Are air quality levels in Water Works Park based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
