MIDAS Open: UK mean wind data, v202207

The UK mean wind data contain the mean wind speed and direction, and the direction, speed and time of the maximum gust, all during 1 or more hours, ending at the stated time and date. The data were collected by observation stations operated by the Met Office across the UK and transmitted within the following message types: SYNOP, HCM, AWSHRLY, DLY3208, HWNDAUTO and HWND6910. The data spans from 1949 to 2021. This version supersedes the previous version of this dataset and a change log is available in the archive, and in the linked documentation for this record, detailing the differences between this version and the previous version. The change logs detail new, replaced and removed data. These include the addition of data for calendar year 2021. For further details on observing practice, including measurement accuracies for the message types, see relevant sections of the MIDAS User Guide linked from this record (e.g. section 3.3 details the wind network in the UK, section 5.5 covers wind measurements in general and section 4 details message type information). This dataset is part of the Midas-open dataset collection made available by the Met Office under the UK Open Government Licence, containing only UK mainland land surface observations owned or operated by the Met Office. It is a subset of the fuller, restricted Met Office Integrated Data Archive System (MIDAS) Land and Marine Surface Stations dataset, also available through the Centre for Environmental Data Analysis - see the related dataset section on this record.本英国平均风数据集包含平均风速与平均风向，以及最大阵风的风向、风速及发生时刻，所有统计时段时长均为1小时及以上，且统计时段结束于指定的日期与时刻。本数据集数据由英国气象局（Met Office）在英国全境布设的观测站采集，并通过以下报文类型传输：SYNOP、HCM、AWSHRLY、DLY3208、HWNDAUTO与HWND6910。数据集的时间覆盖范围为1949年至2021年。本版本已替代该数据集的既往版本，存档文件及本记录的关联文档中均提供更新日志，用以详述本版本与既往版本的差异内容。更新日志列明了新增、替换与移除的数据条目，其中包含2021日历年的观测数据增补。如需了解观测操作规范（包括各报文类型的测量精度）的更多细节，请查阅本记录关联的《MIDAS用户指南》相关章节：例如第3.3节详述英国风观测网络，第5.5节概述通用风速风向测量工作，第4节说明报文类型相关信息。本数据集属于英国气象局依据《英国开放政府许可》发布的Midas-open数据集合集，仅包含英国气象局所有或运营的英国本土陆面观测数据。本数据集为内容更完整的受限访问版英国气象局综合数据存档系统（MIDAS）陆地与海洋地面站数据集的子集，该受限数据集同样可通过环境数据分析中心获取，详情请查阅本记录的关联数据集章节。
