Abstract

This paper mainly studies the relationship between CO2 absorption coefficient and temperature under low temperature conditions. Firstly, based on HITRAN database, this paper determines that the best detection peak of CO2 is located at 1572.34nm. Then, it obtains a general expression between the absorption coefficient and the temperature. And this expression is fitted and analyzed by two different methods. Finally, the derived formula is used to correct the literature data with an error of 0.516% in the paper.
