Portmore's air quality reflects the greater Kingston metropolitan area's southern suburban position on the Portmore peninsula adjacent to the Kingston Harbour, with vehicle traffic on surrounding roads and the dense residential and commercial character contributing local sources. The Caribbean trade winds provide background ventilation, while the Kingston Harbour's industrial waterfront creates background maritime emissions and Portmore generally maintains moderate Jamaican metropolitan southern suburban readings throughout most of the year.

Are air quality levels in Portmore 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.
