PGS
Precision Carbon Dioxide Mixing Ratio System
Baseline Instrument
The precision gas system (PGS) is an atmospheric trace gas monitoring system, measuring continuous CO2 and CH4 at tower sample heights of 2m, 4m, 25m, and 60m above ground level. 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.
