Worldwide Pollution (Sentinel-5P)

Objective, comparable air-quality intelligence — the trace gases that define air quality, worldwide, daily, as absolute readings and change vs last year.

Sentinel-5P measures the trace gases that define air quality from orbit, worldwide, every day: NO₂ (traffic/combustion), SO₂ (power/industry), CO, CH₄, HCHO and aerosols. ETD delivers this in two complementary views: the absolute reading for each gas, and the delta against the same period last year, so seasonal cycles cancel and genuine change stands out. A factory coming online, a traffic rebound, an industrial shutdown or a multi-year trend surfaces as a clear anomaly — global coverage, daily refresh, no ground sensor network.
