About this chart

The observed line is the hourly median across reporting monitors and the shaded range shows local variation. NASA GEOS-CF, CAMS and SILAM are separate total surface PM2.5 research forecasts sampled near the reporting-monitor centre. They are not smoke-only, official health forecasts or blended with observations.
