干旱区生态环境知识资源中心

The vertical structure of a Saharan dust event, occurred at the end of VELETA-2002 campaign, has been documented by means of a lidar system and various sunphotometers among other instruments used in the campaign. Simultaneously to Lidar measurements an AERONET CIMEL sunphotometer provided the aerosol volume size distributions and aerosol optical depth, as reliable determined parameters. The presence of dustrich elevated layers affected the size distribution calculated by the inversion code. In this work, we present a preliminary analysis of the effect of elevated dust-rich layers on the volume size distribution of aerosols retrieved by inversion of the Sun/sky irradiance. This study case shows the characteristics of weak summer desert outbreak over the South of Spain.
