Data details: about this air quality estimate
Values are modeled by the Copernicus Atmosphere Monitoring Service (CAMS) global forecast, extracted and converted by Skymory for this city. They are model estimates on a coarse grid, not measurements from monitoring stations, and they do not resolve street-level exposure.
- Model initialization: 2026-10-01T12:00:00+00:00. Values valid: Oct 02 15:00 AWST. Retrieved: 2026-10-02T04:16:15.177651+00:00.
- Page generated from a snapshot with data state STALE_USABLE; model age 19.9 hours at generation.
- Nearest valid 0.4° model grid cell, about 14 km from the city point.
- Gases are converted with matching model-level 137 temperature, humidity, surface pressure (lnsp) and hybrid coefficients; particulate matter is read directly from the surface fields.
- AQI estimate completeness: COMPLETE (COMPLETE means all six pollutants have a complete model window).
The AQI estimate applies EPA breakpoints (May 2026) to explicit trailing model windows (PM 24 h, CO 8 h, NO2 1 h, SO2 and O3 per EPA rules). It is not a station observation, official daily maximum or NowCast, and the official AQI field remains unavailable.
Averaging windows used
- CO: 8h window
- NO2: 1h window
- O3: 1h, 8h window
- PM10: 24h window
- PM2.5: 24h window
- SO2: 1h, 24h window
Surface compatibility by pollutant
