Area index

55 · Moderate

Measured, not modeled. AirNow observations are preliminary until the operating agency certifies them, which happens months later.

Louisiana Department of Environmental Quality's own forecast for Lake Charles, written by a forecaster rather than read off a model.

Written by Louisiana Department of Environmental Quality for Lake Charles and filed with AirNow.

NOAA’s National Air Quality Forecast Capability, bias-corrected against monitors, for this town’s own coordinate. The worst hour ahead is an index of 55, Moderate, around Tue, 3:00 AM CDT, from the run issued Tue, 1:00 AM CDT. This is a model, not a measurement.

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.

NOAA’s analysts have not drawn smoke over Jasper County in satellite imagery today.

NOAA’s model forecasts near-surface smoke peaking at 1.9 µg/m³ around Wed, 9:00 AM CDT.

Index range

51 to 100

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.
