Abstract: (1960 Views)
A ground-based remote sensing station was installed on the Urmia Lake coast for atmospheric studies in October 2018. The station is equipped with a scanning LiDAR. The studies on this station show, in the warm days of the year, the particles with a volume depolarization ratio of 10 to 20 percent enter the atmosphere. At this time, the atmospheric extinction coefficient was changing from 0.001 to 0.003 m-1. These particles are mainly observed in the heights below 500 meters in the atmosphere. The surface wind speed affects the occurrence of atmospheric phenomena that are rising from the ground up to a height of 1000 meters. Rainfalls affect the height and type of these aerosols and cause them to settle.
Keywords: aerosols, Urmia Lake, extinction coefficient, volume depolarization ratio, ground-based scanning LiDAR.
