Tracking Nitrous Oxide in the Atmosphere
N₂O is the forgotten greenhouse gas — 273× more potent than CO₂ over 100 years, with a 109-year atmospheric lifetime. Our research portal monitors concentrations, maps emission sources, and tracks mitigation progress.

Monitoring
Global atmospheric N₂O monitoring relies on a network of ground-based stations, flask sampling programs, and increasingly, satellite observations. Three major networks form the backbone of…
