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 ...
