The forecaster’s discussion

Written by Arizona Department of Environmental Quality for Nogales and filed with AirNow.

PM10 and PM2.5 were in the Good AQI range yesterday. Overall, today could see brief increases in PM10 due to stronger winds associated with the continuing rain. Drier conditions return Wednesday, and winds will be light until Friday when east winds strengthen. PM10 daily levels are forecast to remain in the Good AQI range, and PM2.5 will have similar trends.

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.
