GB-Swindon: UKRI-2813 Atmospheric Gases Detector

Open-path gas sensor that uses mid-infrared laser dispersion spectroscopy to make highly sensitive, calibration-free atmospheric concentration measurements of both carbon dioxide (CO2) and methane (CH4). The use of laser dispersion spectroscopy is required as it makes the instrument highly immune to fluctuations in laser power, and thereby enables operation in a wide range of weather conditions.
