The forecaster’s discussion

Written by Delaware Dept. of Natural Resources and Environment for Sussex County and filed with AirNow.

Monday, September 21 through Wednesday, September 23: As strong surface high pressure builds to the north and a low pressure system develops off the Carolina Coast, moderate and gusty northeasterly winds will usher a clean, cool air mass into the First State. Additionally, clouds and rain showers will continue to inhibit ozone formation. As a result, AQI levels are anticipated to be Good for ozone and PM2.5 on all three days.

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.
