Abstract: (598 Views)
ISPL, the polarization LiDAR station of IASBS, is located on the west coast of Urmia Lake (UL). This station was set up in October 2018 to study the atmosphere of UL. In this article, using ISPL, we investigate the long-range dust layer transferred to the UL atmosphere. The dust layer was observed by the ISPL on October 24-25, 2021 at an altitude of 4-8 km. The volume depolarization ratio (VDR) of this layer is more than 20%. Whereas the VDR of aerosols at altitudes below 2 km is less than 20%. The results show that the type of aerosols transferred from neighboring dust sources (Saharan Africa) is different from aerosols from the UL basin. In this event, the concentration of aerosols at low altitudes is higher than aerosols at altitudes above 4 km.
