Caloocan City's air quality reflects Metro Manila's northern urban corridor adjacent to Malabon, with vehicle traffic on surrounding roads and the extraordinary jeepney, tricycle, and vehicle density generating elevated PM2.5 and NOₓ. Consistent Philippine Sea trade winds provide maritime ventilation, while the Metro Manila basin's partial enclosure concentrates emissions under calm conditions and Caloocan generally maintains moderate to elevated Manila metropolitan northern corridor readings throughout most of the year.

Are air quality levels in Caloocan City 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.
