Synergistic investigation of the Polar sky

During the Polar night, a combined measurement campaign took place in Ny Ålesund, Svalbard. German, Greek and Italian scientists cooperated. Their goal is to better understand the properties of atmospheric aerosols, tiny particles floating in the air. For this reason, they used different measurement techniques. The laser beam of "KARLi", the Koldewey Aerosol Raman Lidar, was travelling through the atmosphere and when it was scattered backwards scientists collected information about the aerosol concentration in the sky. At the same time, in-situ sensors installed on the tethered balloon Flying Mozzarella, captured aerosols in their filters. Filter analysis is going to reveal the chemical composition and the size of the aerosols. The combination of different measurement techniques aims to complete the puzzle of the aerosol role in the Arctic climate system.
