Aerosols of Saharan dust observed with the Lidar PollyXT System of NOA-ReACT over Antikythera

Transfer of Saharan dust over the island of Antikythera, as observed with the Lidar Polly XT system of the NOA-ReACT team. The signal from the lidar presents a 2 km thick layer (at a height of 7 to 9 km above the ground), which contains dust particles, as shown by 3-day reversals calculated with the Hysplit model. 

Later that day, ice crystal clouds began to form on the layer of the dust particles, which act as ice nuclei. It is worth noting that in the total of 2 years of operation of NOA lidar system in Crete and Antikythera, this is the first time that such a thick layer of dust has been detected at such high altitudes.
