Vertical Distribution of Ice in Arctic Clouds (VERDI) is the name of a German research project to investigate arctic clouds, which took place under the direction of the University of Leipzig in April / May 2012. The aim of the measurements was to improve knowledge about the effects of clouds in the arctic climate system. The main question was aimed at the distribution of ice crystals and water droplets within the clouds, which can vary depending on the temperature and the formation mechanisms of the clouds.

Measurements

During VERDI, clouds were observed with the help of aircraft measurements and their properties were characterized in detail. On the one hand, remote sensing methods (passive and active) were used to map the clouds over a large area. On the other hand, the number and size of cloud droplets and ice crystals within the cloud were measured. The measurements were carried out with the research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research (AWI) , which was stationed in Inuvik / Canada during the measurements . The measurement area comprised the southeastern Beaufort Sea north of the Mackenzie Delta in northwestern Canada. A total of 16 flights were carried out between April 21 and May 17, 2012.

advancement

VERDI was funded by the Alfred Wegener Institute for Polar and Marine Research, the German Research Foundation (DFG) , the Research Center Jülich (FZJ) and the Karlsruhe Institute of Technology (KIT) . Other institutes involved were the Max Planck Institute for Chemistry in Mainz, the Johannes Gutenberg University Mainz and the Institute for Atmospheric Physics at DLR . Logistic support was provided by the Aurora Research Institute in Inuvik, which provided office space and accommodation.
