Long Beach's air quality faces significant challenges from the San Pedro Bay complex, with one of the world's busiest container port operations and the adjacent Los Angeles-Long Beach shipping lane generating sustained diesel PM2.5 and NOₓ from vessel, truck, and terminal equipment emissions. The South Bay's position in the Los Angeles basin's inversion zone compounds the industrial pollution burden from the port corridor.

The mountains ringing the basin can trap pollution close to the ground for days when winds are calm.
Are air quality levels in Long Beach 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.
