The forecaster’s discussion

Written by Forsyth County Office of Environmental Assistance and Protection for Forsyth County-Winston-Salem-Greensboro-High Point and filed with AirNow.

Clouds and scattered showers, throughout the Triad Tuesday, have limited ozone and particle pollution to code GREEN. Clouds will persist, Wednesday and Thursday, along with a good chance of rain. Under these conditions, the AQI will remain low and code GREEN, both days. Sunshine will return, Friday, but a steady, clean, NE flow, will provide cooler temperatures, and GOOD air quality to wrap up the work week (GENTRY; gentrycd@forsyth.cc).

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

NOAA’s Hazard Mapping System analysts drew medium smoke over Stokesdale in satellite imagery today (Tue, 11:00 AM EDT to Tue, 1:00 PM EDT). That is smoke seen from above; it is not always smoke at ground level.

NOAA’s model forecasts near-surface smoke peaking at 0.6 µg/m³ around Mon, 11:00 PM EDT.

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.
