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/<strong>数据集摘要</strong> 本数据集包含一份地面气旋掩膜（surface cyclone mask）数据，记录了南极环极考察（Antarctic Circumnavigation Expedition, ACE）航线上的地面气旋存在情况。本数据集采用欧洲中期天气预报中心（European Centre for Medium-Range Weather Forecasts, ECMWF）的全球业务分析数据，运用二维气旋识别算法（2D cyclone identification algorithm）（Wernli与Schwierz, 2006; Sprenger等, 2017）计算得到地面气旋信息。 <strong>数据集内容</strong> - cyclone_mask_1h.csv：数据文件，格式为逗号分隔值（comma-separated values, CSV） - data_file_header.txt：元数据（metadata）文件，纯文本格式 - README.txt：元数据文件，纯文本格式 <strong>数据集许可</strong> 本ACE地面气旋掩膜数据集采用知识共享署名4.0国际许可协议（Creative Commons Attribution 4.0 International License, CC BY 4.0）发布，协议完整文本可访问https://creativecommons.org/licenses/by/4.0/查阅。
