Laredo's air quality faces the unique challenge of one of the US-Mexico border's busiest commercial crossings, with the World Trade Bridge and Colombia Solidarity Bridge generating massive concentrations of diesel truck emissions from international freight traffic that represents one of Texas' most significant localised pollution point sources. The flat South Texas brush country generally provides reasonable wind dispersal, while cross-border industrial emissions from Nuevo Laredo compound the local air quality burden.

When is air pollution at its worst in Laredo?
Laredo sees air quality change through the year, as the mildest, cleanest stretch typically falls in spring or autumn; by contrast, long, hot summers bring the highest ozone risk, especially across the major urban corridors. Dust from West Texas can occasionally drift across the state and add to particulate levels.
Are air quality levels in Laredo 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.
