Paper Abstract

A method for the measurements of atmospheric transmittance by FTIR spectrometer is proposed. Calibrating special response of system based on two-point temperature with blackbody, transmittance spectra of CO2 IR absorption band are analyzed and calculated depending on the measurement data. The CO2 concentration in atmosphere is acquired after fitting the measured spectra with the line parameter in HITRAN employing NLLS algorithm. The results agree with the standard CO2 concentration considered in the environmental monitoring. It indicates that the method is feasible for measuring atmospheric transmittance and analyzing gases in quantity.
