Greenhouse Gas Monitor

Baseline Instrument, Guest

The greenhouse gas (GHG) measurement system is an atmospheric trace gas monitoring system, measuring continuous CO₂ and CH₄ at a tower sample height of 10m above ground level, formerly as part of the aerosol observing system at the Oliktok Point and Eastern North Atlantic sites. It is a combination of two systems: (1) gas processing components that control moisture and pressure and coordinate measurements of calibration cylinders, and (2) the Cavity Ringdown Spectrometer produced by Picarro, Inc.
