(UV, VIS) Laboratory evaluation of the lidar depolarization ratio of freshly emitted soot aggregates from pool fire in ambient air at exact backscattering angle

•A laboratory experiment is performed to measure soot depolarization at 180.0°.•Fresh soot lidar depolarization ratios are provided in laboratory at 355, 532 nm.•The soot aggregates are freshly emitted from a pool fire in laboratory ambient air.•The soot LDR is numerically computed by applying the Superposition T-Matrix method.•The soot parameters agreeing with the laboratory LDR are hence discussed.
