El Paso's San Jacinto Plaza air quality reflects the historic downtown El Paso urban park, with vehicle traffic on the surrounding Mesa Street corridor and the concentrated downtown commercial character contributing local sources. The Franklin Mountains to the north and the Juárez Mountains across the border create topographic variation, while cross-border vehicle and industrial emissions from Ciudad Juárez on southerly winds and the flat Rio Grande valley contribute to the local air quality background throughout the year.

When is air pollution at its worst in San Jacinto Plaza?
Air quality around San Jacinto Plaza changes with the seasons. In short, the mildest, cleanest stretch typically falls in spring or autumn, whereas long, hot summers bring the highest ozone risk, especially across the major urban corridors. Gulf Coast humidity and inland heat can each add their own seasonal pollution patterns.
Are air quality levels in San Jacinto Plaza 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.
