Mineral dust emissions mainly depend on soil erodibility and near-surface wind speeds. During biomass burning episodes, pyroconvection locally generates high surface wind speed and non-desert surfaces (such as forest and shrubs) are partially replaced by barren soil. These…

Abstract. Wildfire smoke is known as a highly absorptive aerosol type in the shortwave wavelength range. The absorption of Sun light by optically thick smoke layers results in heating of the ambient air. This heating is translated into self-lofting of the smoke up to more than 1…
