Air Quality Index

How's the Air Right Now?


The Air Quality Index: The Current Air Quality

The SkyCast gives us the ground-level ozone forecast. It’s not always easy to tell what the current air quality conditions are. The Air Quality Index (AQI) tells us the air quality based on pollution measurements from the previous day and probable weather conditions.

 

Reading the AQI

The Air Quality Index and the SkyCast use the same color scale with the same meanings.  The AQI also gives us a numeric value that estimates the presence of ozone in parts per billion (ppb).
