Summary raw meteorological data from the Southern Ocean collected on board the Antarctic Circumnavigation Expedition (ACE) during the austral summer of 2016/2017.

<strong>Dataset abstract</strong> A Vaisala MAWS240 meteorological station was installed on the R/V Akademik Tryoshnikov during a circumnavigation of Antarctica in the austral summer season of 2016/2017. This dataset contains the raw meteorological data that have been extracted from the original raw text data files. Data coverage is from 17th November 2016 until 11th April 2017, with gaps where the ship was in port. Air temperature, relative humidity, dew point, solar radiation, ultraviolet radiation, cloud level and sky cover were recorded with a resolution of 30 seconds. Averaged wind parameter data are provided. Date_time should be combined with TIMEDIFF to convert it to UTC. Latitude and longitude recorded are not corrected. Underway seawater measurements were recorded as null values. Data from this dataset have been corrected and quality-checked in another published dataset. We recommend these data for further use (Landwehr et al., 2019; DOI 10.5281/zenodo.3379590). <strong>Dataset contents</strong> metdata_all_YYYYMMDD_YYYYMMDD.csv, data file, comma-separated values data_file_header, metadata, text format README.txt, metadata, text format ace_meteorology_raw_summary_change_log.txt Data files contain data for each leg of the Antarctic Circumnavigation Expedition (ACE). Dates included in the file name are the start and end dates of the legs and therefore the data within the files as well. <strong>Change log</strong> <strong>v1.2</strong> - Added missing data from 2017-02-05 - 2017-02-08 inclusive. Updated this change log file. <strong>v1.1</strong> - Added additional data coverage from 2016-11-17 - 2016-11-22 inclusive, into the first data file. Updated README.txt with information about data coverage. Added this change log file. <strong>v1.0</strong> - Initial release of raw summary meteorological data. <strong>Dataset license</strong> This raw meteorological dataset 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> 2016/2017年南半球夏季期间，“特廖什尼科夫院士”号科考船（R/V Akademik Tryoshnikov）在南极环航任务中搭载了维萨拉MAWS240气象站。本数据集包含从原始文本数据文件中提取的原始气象数据。数据覆盖时段为2016年11月17日至2017年4月11日，船舶停靠港口期间存在数据缺失。观测要素涵盖气温、相对湿度、露点、太阳辐射、紫外线辐射、云高与云量，采样分辨率为30秒。数据集同时提供平均风参数数据。需将Date_time字段与TIMEDIFF字段结合，方可转换为协调世界时（Coordinated Universal Time, UTC）。记录的经纬度未做校正。航行中海水观测数据均以空值记录。本数据集的数据已在另一篇已发表的数据集中完成校正与质量核查，推荐将该数据集用于后续研究（Landwehr等，2019；DOI 10.5281/zenodo.3379590）。 <strong>数据集内容</strong> 包含以下文件： 1. metdata_all_YYYYMMDD_YYYYMMDD.csv：数据文件，采用逗号分隔值（Comma-Separated Values, CSV）格式； 2. data_file_header：元数据文件，文本格式； 3. README.txt：元数据文件，文本格式； 4. ace_meteorology_raw_summary_change_log.txt：变更日志文件。 所有数据文件涵盖南极环航考察（Antarctic Circumnavigation Expedition, ACE）各航段的观测数据，文件名中的日期为对应航段的起始与结束日期，文件内的数据时段与该航段时段完全匹配。 <strong>变更日志</strong> <strong>v1.2</strong> - 补充2017年2月5日至2017年2月8日（含首尾两日）的缺失数据，并更新本变更日志文件。 <strong>v1.1</strong> - 向首个数据文件中补充2016年11月17日至2016年11月22日（含首尾两日）的覆盖数据，更新README.txt以补充数据覆盖范围信息，并新增本变更日志文件。 <strong>v1.0</strong> - 原始汇总气象数据首次发布。 <strong>数据集许可协议</strong> 本原始气象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/ 查询。
