Area index

23 · Good

Measured, not modeled. AirNow observations are preliminary until the operating agency certifies them, which happens months later.

Virginia Dept. of Environmental Quality's own forecast for Richmond, written by a forecaster rather than read off a model.

NOAA’s National Air Quality Forecast Capability, bias-corrected against monitors, for this town’s own coordinate. The worst hour ahead is an index of 24, Good, around Tue, 4:00 PM EDT, from the run issued Tue, 11:00 PM EDT. This is a model, not a measurement.

Fine particles in micrograms per cubic meter, ozone in parts per billion as an 8-hour average. The index for each hour is EPA’s: the ozone figure is already the 8-hour average the ozone index is defined on, and the particle figure is run through EPA’s NowCast, which is how an hourly PM2.5 concentration becomes an index.

NOAA’s Hazard Mapping System analysts drew light smoke over Charles City County in satellite imagery today (Tue, 1:00 PM EDT to Tue, 4:00 PM EDT). That is smoke seen from above; it is not always smoke at ground level.

NOAA’s model forecasts no measurable smoke near the ground here over the next two days.

Category descriptions are the Environmental Protection Agency’s own.

What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
