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.
