Helicopter lidar project for the remote methane leakage detection based on the TEA CO/sub 2/ laser radiation harmonics

摘要

On the basis of SAGDAM dialogue software package the quantitative estimation of possibilities of remote measurement of methane leakage of various intensity from pipelines at a distance of 1 km using the helicopter DIAL lidar was carried out. It was shown that an application of the third harmonic of TEA CO/sub 2/ laser radiation enables one to identify the concentration of methane emissions with measurement error of 10-15% for the methane content in the atmosphere from background level to close to explosive level.
