Los Angeles' The Broad air quality reflects the Grand Avenue cultural corridor in Downtown Los Angeles, with vehicle traffic on Grand Avenue and the surrounding DTLA commercial and cultural character generating elevated NOₓ. The Bunker Hill's elevated position provides marginally better dispersal than the flat basin floor, while the DTLA cultural corridor and the Los Angeles basin inversion maintain moderate to elevated downtown readings throughout most of the year.

Coastal breezes offer some relief compared to inland valley locations that see heavier smog buildup.
Are air quality levels in The Broad 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.
