Precision Carbon Dioxide Mixing Ratio System (PGS)

Instrument Categories: Atmospheric Carbon

General Overview

Picture of the Precision CO2 Mixing Ratio System (PGS)

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.

Primary Measurements Taken

The following measurements are those considered scientifically relevant. Refer to the netCDF File Header Descriptions (Data Object Design Files) for the list of all available measurements, including those recorded for diagnostic or quality assurance purposes.
