Opo lidar sounding of trace atmospheric gases in the 3 – 4 μm spectral range
EPJ Web of Conferences, 2018 The applicability of a KTA crystal-based laser system with optical parametric oscillators (OPO) generation to lidar sounding of the atmosphere in the spectral range 3–4 μm is studied in this work.

Imaging of Atmospheric Dispersion Processes with Differential Absorption Lidar [PDF]
SIAM Journal on Imaging SciencesWe consider the inverse problem of fitting atmospheric dispersion parameters based on time-resolved back-scattered differential absorption Lidar (DIAL) measurements. The obvious advantage of light-based remote sensing modalities is their extended spatial range which makes them less sensitive to strictly local perturbations/modelling errors or the ...
