Los Angeles' Griffith Observatory air quality benefits from its elevated Hollywood Hills position at 300 metres, with the elevated position above the Los Angeles basin inversion layer providing among the metropolitan area's better conditions on most days. Vehicle traffic on the winding observatory access road contributes modest local sources, while the elevated chaparral hillside position provides substantially better dispersal than the flat basin floor and the observatory generally maintains among LA's more reliably ventilated major cultural landmarks throughout most of the year.

Are air quality levels in Griffith Observatory 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.
