The greenhouse gas (GHG) measurement system is a combination of two systems in series: (1) the tower gas processing (TGP) system, an instrument rack that pulls, pressurizes, and dries air streams from an atmospheric sampling tower through a series of control and monitoring components, and (2) the Picarro model G2301 cavity ringdown spectrometer (CRDS), which measures CO2 and CH4, the primary measurements of the GHG system.
