[{"name":"oden-ao-2018-cloudnet-4","title":"Cloudnet remote sensing retrievals of cloud properties during the Arctic Ocean 2018 expedition","summary":"This dataset consists of a range of output products from the Cloudnet algorithm. Cloudnet combines cloud radar, ceilometer, microwave radiometer, and radiosonde profiles averaged to a common grid at the cloud radar resolution to derive a set of retrieved cloud properties. These include: (1) macrophysical properties such as cloud base and top heights, liquid and ice water paths, (2) cloud fraction, (3) microphysical particle classifications such as ice, liquid, mixed-phase, and aerosol, (4) estimates of particle effective radii, liquid and ice water contents, and precipitation rates.\r\n\r\nThe Cloudnet products are designed to be used for evaluation of weather forecast models as well as fundamental process studies of cloud.\r\n\r\nThis dataset derives from measurements made during the Arctic Ocean 2018 expedition on icebreaker Oden during summer 2018 (August 1\u2060\u200a\u2013\u200a\u2060September 21). Data is presented on a 30-second time base, and approximately 24 m vertical resolution.","citations":"V\u00fcllers J, Achtert P, Brooks IM, Tjernstr\u00f6m M, Prytherch J, Burzik A, Neely III R (2021) Meteorological and cloud conditions during the Arctic Ocean 2018 expedition.
