Alerts in force

An Air Quality Alert is issued by the National Weather Service on behalf of a state or local agency when pollution is expected to reach a level that harms health. An Air Stagnation Advisory means the air will not move enough to clear what is already in it.

None are in force near Gambier right now. All Ohio warnings.

The forecaster’s discussion

Written by MORPC for Columbus and filed with AirNow.

Saturday, September 19: Light southeasterly morning winds will transport pollutants into the Columbus region. In addition, periods of sunshine will aid ozone production. However, afternoon showers will enhance mixing and limit ozone formation, keeping AQI levels Good. Sunday, September 20: As a surface low pressure system moves across the Columbus region, atmospheric mixing and dispersion will increase. Additionally, clouds and rain showers will inhibit ozone formation. However, periods of westerly winds will bring regional pollutants into the area, yielding high-Good AQI levels. Monday through Wednesday, northeasterly to easterly winds will transport clean, cool air into central Ohio, while mostly cloudy skies and showers will limit ozone development. Therefore, AQI levels will remain Good on all three days. Thursday, as a low pressure system stalls over southwest Ohio, southeasterly winds will carry regional pollutants into central Ohio. However, clouds and showers will continue to inhibit ozone formation, and pollutant carryover from previous days will be low. Therefore, AQI levels will be high-Good.

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.

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.
