Field Test of a Remote Multi-Path CLaDS Methane Sensor

Sensors (Basel). 2015 Aug 28;15(9):21315-26. doi: 10.3390/s150921315.


Existing technologies for quantifying methane emissions are often limited to single point sensors, making large area environmental observations challenging. We demonstrate the operation of a remote, multi-path system using Chirped Laser Dispersion Spectroscopy (CLaDS) for quantification of atmospheric methane concentrations over extended areas, a technology that shows potential for monitoring emissions from wetlands.
