PGS

Precision Carbon Dioxide Mixing Ratio System

Baseline Instrument

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.
