IR CO2 MH-Z19D

How Exactly Does Carbon Dioxide Cause Global Warming ...

Feb 25, 2021· Credit: NASA. With CO2 and other greenhouse gases, it’s different. Carbon dioxide, for example, absorbs energy at a variety of wavelengths between 2,000 and 15,000 nanometers — a range that overlaps with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions.

CO2 Absorption Spectrum.

Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are , and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2.
