  AQAMEG The Shelby County Health Department has issued a Code Orange Ozone Health Advisory effective for Shelby County Tennessee, Crittenden County Arkansas, and DeSoto County Mississippi, including the city of Memphis that will remain in effect until sunset. This ozone health advisory is due to monitored ozone values that are unhealthy for sensitive groups. These values have exceeded the Environmental Protection Agency's federal safe health standard. The Shelby County Health Department recommends that sensitive groups which include active children and adults, and people with respiratory disease, such as asthma, limit prolonged outdoor exertion. Please continue to check the latest air quality forecasts and updates until monitored values return to safe levels. For more information go to www.airnow.gov.

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

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 59, Moderate, around Thu, 3:00 AM CDT, from the run issued Mon, 7:00 AM CDT. 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 medium smoke over Bradley County in satellite imagery today (Mon, 12:00 PM CDT to Mon, 3:00 PM CDT). That is smoke seen from above; it is not always smoke at ground level.

NOAA’s model forecasts near-surface smoke peaking at 2.2 µg/m³ around Mon, 12:00 AM CDT.

Index range

51 to 100

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.
