Trujillo's air quality reflects the flat Peruvian northern coastal desert plain at 29 metres on the Pacific, with vehicle traffic on surrounding roads and the vehicle density, manufacturing, and construction corridor generating elevated PM2.5. Consistent Pacific Humboldt Current maritime breezes provide coastal ventilation, while the flat coastal desert terrain allows reasonable dispersal and Trujillo generally maintains moderate Peruvian northern Pacific coastal metropolitan readings throughout most of the year.

When is air pollution at its worst in Trujillo?
Air quality in Trujillo tends to be worse when vehicle traffic, manufacturing activity, as well as construction dust build up and onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Trujillo 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.
