Near-surface ozone pollution, fast satellite view (Copernicus)

Sentinel-5P Level 2 Tropospheric Ozone (NRTI)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. Maps ozone in the lower atmosphere, the troposphere, where we breathe. Down here ozone acts as a pollutant that harms lungs and crops rather than as a shield.

How it's made. Derived from Sentinel-5P satellite measurements, processed to Level-2 in a near-real-time stream delivered within hours.

How & where you'd use it. Useful for monitoring air quality and smog, and for quick situational awareness when pollution events develop.
