ICOS atmospheric stations use cavity ring-down spectroscopy for real-time N\u2082O measurements, complemented by flux tower measurements at ecosystem level. Together, AGAGE, NOAA, and ICOS form an increasingly integrated global monitoring system that is essential for tracking progress toward international climate goals.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Global atmospheric N\u2082O monitoring relies on a network of ground-based stations, flask sampling programs, and increasingly, satellite observations.
