Assimilating spaceborne lidar dust extinction can improve dust forecasts [PDF]
Atmospheric Chemistry and Physics, 2022 Atmospheric mineral dust has a rich tri-dimensional spatial and temporal structure that is poorly constrained in forecasts and analyses when only column-integrated aerosol optical depth (AOD) is assimilated.

Potential of polarization/Raman lidar to separate fine dust, coarse dust, maritime, and anthropogenic aerosol profiles [PDF]
Atmospheric Measurement Techniques, 2017 We applied the recently introduced polarization lidar–photometer networking (POLIPHON) technique for the first time to triple-wavelength polarization lidar measurements at 355, 532, and 1064 nm. The lidar observations were performed at Barbados during

Apparent dust size discrepancy in aerosol reanalysis in north African dust after long-range transport [PDF]
Atmospheric Chemistry and Physics, 2020 North African dust reaches the southeastern United States every summer. Size-resolved dust mass measurements taken in Miami, Florida, indicate that more than one-half of the surface dust mass concentrations reside in particles with geometric diameters ...

Saltation Activity on Non-Dust Days in the Taklimakan Desert, China
Remote Sensing, 2022 Dust aerosols persistently affect nearly all landscapes worldwide, and the saltation activity caused by dusty weather (e.g., dust days) releases considerable amounts of aerosol into the atmosphere.
