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.
