El Paso's Segundo Barrio air quality reflects the historic South El Paso Mexican-American neighbourhood adjacent to the US-Mexico border, with the concentrated international bridge vehicle traffic and cross-border industrial and vehicle emissions from Ciudad Juárez generating elevated PM2.5 and NOₓ. The flat Rio Grande valley's calm conditions can concentrate cross-border and border crossing emissions under inversions, making Segundo Barrio one of El Paso's more persistently challenged border community environments throughout the year.

When is air pollution at its worst in Segundo Barrio?
Air quality around Segundo Barrio changes with the seasons. Typically, the mildest, cleanest stretch typically falls in spring or autumn, while intense summer heat drives persistent ozone problems, particularly in and around the largest metro areas. Gulf Coast humidity and inland heat can each add their own seasonal pollution patterns.
Are air quality levels in Segundo Barrio 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.
