Carbon Dioxide Absorption in the Near Infrared

Due to the increase of anthropogenic carbon dioxide and its highly politicized global effects, there has been much research concerning the absorptivity of CO 2 and its thermal effects. CO 2 contributes to the greenhouse effect by absorbing energy in the infrared (IR) wavelengths, thus trapping heat within the boundaries of the earth’s atmosphere.

How do we know more CO2 is causing warming?

Apr 25, 2014· An enhanced greenhouse effect from CO2 has been confirmed by multiple lines of empirical evidence. Satellite measurements of infrared spectra over the past 40 years observe less energy escaping to space at the wavelengths associated with CO2. Surface measurements find more downward infrared radiation warming the planet's surface. This provides a direct, empirical causal link between CO2 …

Physical Methods of CO2 measurement - Capnography

Photoacoustic gas measurement (, Bruel-Kjaer gas monitor)is based on the same principles as conventional IR-based gas analyzers: the ability of CO 2 and N20 and anaesthetic agents to absorb IR light. However, they differ in measurement techniques. While Infra-red spectrography uses optical methods, PAS uses an acoustic technique.
