AIR QUALITY INDEX
Numbers in the chart below show the Air Quality Index for today, based on an average over time. See AQI Table for how to interpret the colors. The Index numbers represent a ranking for the pollutant, not the measurement of a pollutant. When air quality is expected to be worse — such as during wildfires, which produce elevated levels of particulate matter (PM) — it is important to check hourly readings, which do show the measurement of the pollutant. Hourly readings are available on the Station Data page. The Index below presents ratings for: ozone, a principal component of smog; particulate matter smaller than 10 microns in diameter (PM10); and particulate matter smaller than 2.5 microns in diameter (PM2.5). Note: all data are preliminary and subject to verification. To view exceedances of standards, see Days Exceeding Ozone and Particulate Standards.
Note: Elevated PM10 levels may intermittently occur at our Santa Barbara station, due to emergency vehicles refueling in close proximity to our station. We deeply appreciate the work that first responders are putting in to serve our community during this tragic time. These elevated levels will be temporary and are very localized.
