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

***** Dataset abstract ***** 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). ***** Dataset contents ***** - metdata_all_YYYYMMDD_YYYYMMDD.csv, data file, comma-separated values<br> - data_file_header, metadata, text format<br> - 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. ***** Change log ***** v1.1 - 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. v1.0 - Initial release of raw summary meteorological data. ***** Dataset license***** 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/***** 数据集摘要 ***** 2016/2017年南极夏季环球航行期间，“阿克季什尼科夫院士号”研究船（R/V Akademik Tryoshnikov）上部署了一台维萨拉MAWS240气象站（Vaisala MAWS240 meteorological station）。本数据集包含从原始纯文本数据文件中提取得到的原始气象数据。数据覆盖时段为2016年11月17日至2017年4月11日，船舶停靠港口时段存在数据缺失。 本数据集记录了气温、相对湿度、露点、太阳辐射、紫外辐射、云量层级与天空状况，采样分辨率为30秒，同时提供经平均处理的风参数观测数据。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）。所记录的经纬度未进行校正。航行过程中的海水测量数据均以空值记录。 本数据集的原始数据已在另一篇已发表的数据集中完成校正与质量检验，推荐后续研究使用该数据集（Landwehr等，2019；DOI 10.5281/zenodo.3379590）。 ***** 数据集内容 ***** - metdata_all_YYYYMMDD_YYYYMMDD.csv：数据文件，逗号分隔值（Comma-Separated Values，CSV）格式 - data_file_header：元数据，纯文本格式 - README.txt：元数据，纯文本格式 - ace_meteorology_raw_summary_change_log.txt 所有数据文件均涵盖南极环球航行考察队（Antarctic Circumnavigation Expedition, ACE）各航段的观测数据，文件名中包含的日期即为对应航段的起始与结束日期，文件内的数据时段亦与此完全匹配。 ***** 更新日志 ***** v1.1版本：向首个数据文件中补充了2016年11月17日至2016年11月22日（含首尾两日）的观测数据；更新README.txt文件，补充数据覆盖范围相关说明；新增本变更日志文件。 v1.0版本：原始汇总气象数据的首次正式发布。 ***** 数据集许可 ***** 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）进行授权，协议完整文本可访问https://creativecommons.org/licenses/by/4.0/查阅。
