Image of the week: A new view of global ozone from space

Copernicus Sentinel-5 will monitor air quality, trace gases and aerosols at high spatial resolution with daily global coverage. It will work together with other advanced instruments on Metop-SGA1 — including IASI-NG, METimage, and 3MI — to deliver an unparalleled view of Earth’s atmosphere. The Metop-SGA1 satellite was launched in August 2025.

The image shows a map of global ozone(O₃)and the hole in stratospheric ozone above Antarctica can be seen with lower column density values (dark blue colour). Stratospheric ozone is a protective layer in the atmosphere that shields life on Earth from harmful ultraviolet radiation.

Sentinel-5 observations will be integrated into products from the Copernicus Atmosphere Monitoring Service (CAMS) to provide important insights on trace gases and pollutant concentrations worldwide.
