Journal ArticleDOI

Mineral dust photochemistry induces nucleation events in the presence of SO2

Yoan Dupart, +11 more
- 18 Dec 2012 - 
TL;DR: In this paper, the authors provide evidence for an alternate pathway in which a series of reactions under solar UV light produces first gaseous sulfuric acid as an intermediate product before surface-bound sulfate.
Journal ArticleDOI

Retrieving simulated volcanic, desert dust and sea-salt particle properties from two/three-component particle mixtures using UV-VIS polarization lidar and T matrix

Grégory David, +4 more
- 18 Jul 2013 - 
TL;DR: In this paper, the spectral and polarization properties of the light backscattered by atmospheric particles are analyzed using a dual-wavelength polarization lidar and T-matrix numerical simulations and air mass back trajectories.
Journal ArticleDOI

Sensitive and accurate dual-wavelength UV-VIS polarization detector for optical remote sensing of tropospheric aerosols

Grégory David, +3 more
- 23 May 2012 - 
TL;DR: In this paper, an UV-VIS polarization lidar has been designed and specified for monitoring aerosols in the troposphere, showing the ability to precisely address low particle depolarization ratios, in the range of a few percent.
Journal ArticleDOI

Ultraviolet broadband light scattering for optically-trapped submicron-sized aerosol particles

Grégory David, +3 more
- 10 Feb 2016 - 
TL;DR: It is shown that a broad wavelength range is required to determine the particle radius and the refractive index with an uncertainty of several nanometers and ∼ 0.01, respectively, and the smallest particle radius that can be accurately determined lies around 300 nm.
Journal ArticleDOI

Atmospheric non‐spherical particles optical properties from UV‐polarization lidar and scattering matrix

Alain Miffre, +3 more
- 01 Aug 2011 - 
TL;DR: In this paper, the optical backscattering properties of atmospheric non-spherical particles are analyzed after long-range transport with a highly sensitive and accurate UV-polarization lidar.
