Quick Update Guide
This is raw data. It has not been validated and may contain errors.
- The data is obtained from automated, continuous instruments; no human has reviewed or checked the accuracy of this data.
- The data has been subject to only preliminary automated quality assurance procedures.
- Special conditions such as power outages and equipment malfunction can produce data that is invalid.
- This data is made available for the purpose of public awareness and should not be used in any medical or other scientific study.
- Quality assured data can be obtained by contacting the Missouri Department of Natural Resources Air Pollution Control Program.
All data is recorded using Central Standard Time(CST), not daylight savings time.
The camera page is a quick look at the current pollutant levels of the most common air pollutants.
The camera page is not a complete Air Quality Index Report (AQI) .
The color of the outside columns indicates what the AQI level would be If the the current level of particulate continues for 24-hours, or the current Ozone concentration continues for eight hours.
The concentration units used for ozone are parts per million (PPM)
The concentration units for Particulate matter are micro-grams per cubic meter (µg/m³).
The AQI and its associated health messages are based on long term averages and do not reflect the rapid changes in pollution levels that often occur during the day.
It is hoped that users of the camera page, especially those with existing respiratory and heart problems, may be better able to plan their daily activities by knowing current pollutant concentrations as well as the AQI .
