What this sensor reports

4.0 µg/m³ is Good on the one-hour PM2.5 air quality scale. Current hourly reading.

The sensor belongs to NSW DCCEEW. NSW DCCEEW publishes this site as indicative: it increases spatial coverage but can be more variable and is not a NATA-accredited reference measurement. Use this reading as a guide rather than a precise measurement.

The category applies only to the latest one-hour reading. It follows the Australian enHealth framework used by agencies including NSW, Victoria and Queensland. The NowCast and rolling mean are separately labelled derived concentrations. How the categories are used.

About this chart

Observed values come from this monitor. NASA GEOS-CF, CAMS and SILAM are independent total surface PM2.5 research forecasts sampled from their nearest grid cells; they are not blended with the observations.
