Abstract

Laser heterodyne technology has high spectral resolution characteristics

and it is commonly used for atmospheric measurements

especially in the measurement of total atmospheric transmittance and gas column density inversion. For these reasons

a heterodyne system with a narrow-linewidth 3.53 μm Distributed Feedback Interband Cascade Laser (DFB-ICL) as a local oscillator was designed to measure the absorption spectrum of water vapor and methane in the atmosphere. This system has a spectral resolution of 0.002 cm

-1

and a Signal-to-Noise Ratio (SNR) of 24.9 dB

which meets the requirements for Doppler broadened line shape measurements. The absolute difference between the measured total atmospheric transmittance and the simulated total atmospheric transmittance in the 3.53 μm band is less than 0.1 because of the high capability of laser heterodyne technology for spectrum detection. Therefore

the measured and simulated transmissions have the same overall variation. When combined with the least-squares method

the system realizes the simultaneous inversion of water vapor and methane column density in the atmosphere. The average column density of the water vapor and methane in the Hefei area was 1.20 g/cm

and 1.31 mg/cm

respectively

during the experiments. Based on this work

we have developed methods for improving spectral resolution and the signal-to-noise ratio of a laser heterodyne system

which provides the basis for obtaining more accurate absorption lines and the acquisition of more precise gas density measurements in the atmosphere.
