[−][src]Crate aqi
The aqi crate provides functions for calculating the Air Quality
Index based on concentrations of particuate matter.
The AQI is defined for ozone (O₃), 1.0-2.5 micron particulate matter (PM2.5), 2.5-10 micron particulate matter (PM10), carbon monoxide (CO), sulfur dioxide (SO₂), and nitrogen dioxide (NO₂).
The AQI helps make air quality more understandable to laypersons, normalizing air quality on a scale from 0 to 500, with round-number ranges that indicate qualities such as "Good", "Unhealthy", and "Hazardous".
Further details about AQI in general can be found at https://www.airnow.gov/aqi/aqi-basics/.
Further details about the AQI equation can be found at https://www.airnow.gov/publications/air-quality-index/technical-assistance-document-for-reporting-the-daily-aqi/.
Additionally, this library supports "adjusted" PM2.5 AQI values, using the LRAPA and AQandU conversion formulas.
