The forecaster’s discussion

Written by Maryland Department of the Environment for Metro Baltimore and filed with AirNow.

Pristine air quality conditions are expected for the next few days as strong northeasterly winds tap into clean maritime air, with periods of unsettled weather further scouring pollutants. Good AQI is expected through at least Thursday. For the latest air quality information, please visit our website here. -MDE

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.
