Near-Infrared Off-Axis Integrated Cavity Output Spectroscopic Gas Sensor for Real-Time, In Situ Atmospheric Methane Monitoring

Kaiyuan Zheng et al.

Summary: The study demonstrates a near-infrared methane sensor system using OA-ICOS technology, which shows high accuracy and fast response in real-time ambient atmospheric CH4 monitoring. By applying various denoising algorithms and dual-gas sensing technology, the precision levels of CH4 measurements were successfully improved. The experimental results indicate that this sensor system has high accuracy and reliability in monitoring CH4 at ppbv levels.
