Conroe's air quality reflects its position north of Houston in Montgomery County, with vehicle emissions from I-45 and the surrounding suburban and commercial growth 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 Sam Houston National Forest nearby provides a clean-air buffer.

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.
