Weather & Air Quality in East Saint Louis, IL (62201)

Q: What is the primary air pollutant in East Saint Louis, TX?

The primary pollutants monitored in East Saint Louis include Fine Particulate Matter (PM2.5), Coarse Particulate Matter (PM10), Ground-level Ozone (O3), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), and Sulfur Dioxide (SO2).

Q: Is it safe to exercise outdoors today in East Saint Louis (75201)?

Outdoor exercise safety in East Saint Louis depends on real-time Air Quality Index (AQI) values. Levels below 50 are safe for all groups, while levels above 100 suggest sensitive individuals should limit prolonged exertion.

How Weather Data is Calculated

Weather measurements on AQIFinder.com are computed via high-resolution numerical weather prediction models and meteorological station observations provided directly through open API data sources.

1. Temperature & Atmospheric Physics

Air temperature measurements are recorded in degrees Celsius (°C). Sensors utilize radiation shields to filter interference from solar reflection, guaranteeing precise ambient readings.

2. Integration with Air Quality (AQI)

Atmospheric dynamics like boundary layer height, temperature inversions, and local wind fields directly determine particulate dispersal (PM2.5 / PM10) and chemical pollutant behavior.
