pgs > Precision Carbon Dioxide Mixing Ratio SystemInstrument Type(s) > Baseline

This precision gas system (PGS) makes high-accuracy, high-precision measurements of CO2 mixing ratio (ppmv dry air) in air sampled at 2, 4, 25, and 60 m above the ground.

Specifically, PGS measures atmospheric moisture, CO2 concentration, and methane concentration.
