Investigating the dependence of mineral dust depolarization on complex refractive index and size with a laboratory polarimeter at 180.0° lidar backscattering angle by A. Miffre, D. Cholleton, C. Noël, P. Rairoux

“…Our <span class="inline-formula"><i>π</i></span>-polarimeter provides 16 accurate (<span class="inline-formula">&lt;1</span> %) values of the dust lidar PDR at 180.0<span class="inline-formula">^∘</span> corresponding to four different complex refractive indices, studied at two size distributions (fine, coarse) ranging from 10 nm to more than 10 <span class="inline-formula">µm</span> and at (355, 532) nm wavelengths while accounting for the highly irregular shape of mineral dust, which is difficult to model numerically. …”
