Vertical gradient of dust extinction coefficient detected by AD-Net lidars in Japan

Key Points

To assess the vertical gradient of dust extinction coefficient and its environmental impact on human health.
Utilized the Asian dust and aerosol lidar observation network (AD-Net) in Japan.
Analyzed meteorological parameters related to dust layers.
Investigated diurnal variations in boundary layer structure affecting dust transport.
Identified the vertical gradient of dust extinction coefficients.
Demonstrated the influence of boundary layer structure on dust particle movement.
Highlighted the need for accurate chemical transport model validation.

Abstract

The vertical gradient of dust extinction coefficient is crucial to access the environmental impact of Asian dust to human health at the surface, and to validate the accuracy of chemical transport models. Asian dust and aerosol lidar observation network (AD-Net) was utilized to detect Asian dust cases in Japan and meteorological parameters were employed to analyze the floating dust layer which is separated from the earth surface. Diurnal variation of boundary later structure is one of mechanisms to convey dust particles in upper layer to the surface.
