pgsiso > Precision Gas System Isotope AnalyzerInstrument Type(s) > Baseline

The precision gas system isotope analyzer (PGSISO) is an atmospheric trace gas monitoring system, measuring continuous CO2, 12CO2, 13CO2, CH4, CO, N2O, and H2O at tower sample heights of 2m, 4m, 25m, and 60m above ground level. It is a combination of several systems in series: (1) gas processing components that pressurize and prevent liquid water into the sample stream, as well as for coordinating automated measurements of calibration cylinders, and (2) the Spectronus FTIR spectrometer developed by Ecotech Pty Ltd.
