Surface cyclone mask for the Antarctic Circumnavigation Expedition from December 2016 – March 2017.

<strong>Dataset abstract</strong> This dataset contains a surface cyclone mask, which records the presence of a surface cyclone along the track of the Antarctic Circumnavigation expedition (ACE). The surface cyclones are calculated applying a 2D cyclone identification algorithm (Wernli and Schwierz, 2006; Sprenger et al., 2017) using global operational analysis data of the European Centre for Medium Range Weather Forecasts. <strong>Dataset contents</strong> - cyclone_mask_1h.csv, data file, comma-separated values<br> - data_file_header.txt, metadata, text<br> - README.txt, metadata, text <strong>Dataset license</strong> This surface cyclone mask dataset from ACE is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) whose full text can be found at https://creativecommons.org/licenses/by/4.0/
