Spring's air quality reflects its position north of Houston in Harris County, with vehicle emissions from I-45 and the surrounding suburban and commercial development contributing local sources. Gulf of Mexico southerly breezes provide warm-season ventilation, while the Houston Ship Channel petrochemical complex upwind contributes industrial background emissions under northerly wind conditions and the flat Gulf coastal terrain generally allows reasonable dispersal throughout the year.

When is air pollution at its worst in Spring?
Spring's air quality follows a clear seasonal pattern. In short, between summer heat and winter cedar season, spring and fall offer the most moderate conditions, whereas extended summer heat waves bring the year's worst ozone readings in the state's biggest metro areas. Gulf Coast humidity and inland heat can each add their own seasonal pollution patterns.
Are air quality levels in Spring 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.
