The AQI tells us how clean or dirty the air is, like a report card for the sky.
Imagine you're playing outside on a sunny day, and suddenly it gets smoky, that’s when the air isn’t as clean as it should be. The AQI, or Air Quality Index, helps people know if it's safe to play, walk, or even breathe deeply.
How It Works
Think of the AQI like a traffic light.
- If the light is green (like 0, 50), that means the air is very clean, perfect for running around!
- If it turns yellow (like 51, 100), the air is still okay, but you might feel a little more tired if you're playing hard.
- When it’s red (like 151, 200), that means the air has a lot of dirt or smog, maybe it's better to stay inside and read a book instead.
The AQI measures things like smog, pollen, and dust in the air. These are like invisible friends or enemies that can make your nose tickle or your throat feel scratchy.
So, the next time you're outside, remember, the AQI is like a weather report for your lungs!
Examples
- A city's AQI goes up because of heavy traffic on weekends.
