Sentinel‑4 Delivers First Images of NO2, SO2 and Ozone After July Launch

Sentinel‑4 has produced its first images after a July launch, mapping atmospheric concentrations of nitrogen dioxide, sulphur dioxide and ozone. The initial dataset provides space‑based observations of pollutant distributions for air‑quality monitoring and marks the satellite's handover into operational atmospheric composition monitoring.

Briefing

What Hype is tracking

  • Sentinel‑4’s first images provide the initial space‑based maps of nitrogen dioxide, sulphur dioxide and ozone following its July launch, creating a baseline dataset for atmospheric composition and air‑quality monitoring.
  • The delivery of these observations arrives amid broader Earth‑observation activity, building on Europe’s recent MetOp‑SG A1/Sentinel‑5 deployment (https://hype.aero/?story=ba174a72-f1e6-46c3-bb94-870c31947636), Vega C’s CO2‑mapping and Earth‑observation launches (https://hype.aero/?story=b11f8410-4c36-4d60-973d-d91327c7e019) and the expansion of satellite+AI pollution mapping (https://hype.aero/?story=26133a57-075b-479b-83b3-627be01ed425).
