QLM Lidar Sees in 3-D

Plume of the Week! QLM’s Quantum Gas Lidar has demonstrated the most accurate quantification performance of any continuous monitoring technology at METEC, but how is that performance achieved? It’s owing to the inherently 3-D quality of the lidar data – the 3D capability of lidar enables extremely accurate plume size measurement and therefore high quantification accuracy. In other words, the system is able to measure the distance to the plume origin and thereby scale the actual, physical size of the plume. Combining that with the measured methane concentration path-length results in effectively being able to calculate the number of methane molecules in the plume.
