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 01:00 CST. Retrieved: 2026-10-02T04:37:16.289878+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 26 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
