Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount of carbon dioxide …
