Des Moines' Ewing Park air quality benefits from the 160-acre South Side park's substantial woodland providing natural filtration. Vehicle traffic on the surrounding Indianola Avenue corridor contributes modest local sources, while the park's woodland canopy generally maintains better conditions than the surrounding dense residential corridors and Ewing Park provides one of Des Moines' more pleasant South Side park environments throughout most of the year.

When is air pollution at its worst in Ewing Park?

Ewing Park experiences the same seasonal air quality swings as the rest of Des Moines: once the harvest dust settles, winter typically offers the cleanest stretch of the year, but summer heat and humidity drive ozone formation, and agricultural dust can spike particulate levels during planting and harvest. Farm-heavy surrounding land is the main source of the seasonal dust spikes.

Are air quality levels in Ewing 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.
