Implication

Novel laboratory methodology evaluates aerosol backscatter and extinction ratios, improving light scattering models.

Key Points

This research aims to propose and validate a new methodology for evaluating the aerosol particle extinction-to-backscatter ratio.
Development of LR-lab methodology based on a light backscatter experiment at 180.0° angle, coupled with cavity ring down experiment.
Validation on homogeneous spherical water droplets using Mie theory for size and concentration variations.
Evaluation of the lidar ratio of mineral dust at 532 nm wavelength through laboratory experiments.
The dust lidar ratio was determined to be (47 ± 2) sr.
The dust depolarization ratio was measured at (33.6 ± 0.4) %.
LR-lab methodology effectively addresses the need for accurate aerosol characterization in light scattering models.
