The forecaster’s discussion

Written by New Jersey Dept. of Environmental Protection for Northeast Urban and filed with AirNow.

9/22 - Unsettled weather returns today as an area of low pressure pushes into the Mid-Atlantic region, resulting in scattered showers, steady northeasterly winds, and cooler temperatures in the low to mid 60s across New Jersey. Air quality will remain in the Good category statewide as a result. 9/23 - A breezy northeasterly/onshore flow will help to keep air quality well into the Good category statewide on Wednesday, accompanied by persistent cool temperatures and lingering morning rain showers.

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.

Smoke

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.
