Measurements of Atmospheric Carbon Dioxide Over Northwestern North America

Measurements of Atmospheric Carbon Dioxide Over Northwestern North America is a differential, non-dispersive, infrared (NDIR) gas analyzer. The CO2 measurements are based on the difference in absorption of infrared(IR) radiation passing through two gas sampling cells. The reference cell is used for a gas of known CO2 concentration, and the sample cell is used for agas of unknown concentration. Infrared radiation is transmitted through both cell paths, and the output of the analyzer is proportional to the difference in absorption between the two.
