MIDAS Open: UK hourly rainfall data, v202107

The UK hourly rainfall data contain the rainfall amount (and duration from tilting syphon gauges) during the hour (or hours) ending at the specified time. The data also contains precipitation amounts, however precipitation measured over 24 hours are not stored. Over time a range of rain gauges have been used - see the linked MIDAS User Guide for further details. 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. The data were collected by observation stations operated by the Met Office across the UK and transmitted within the following message types: NCM, AWSHRLY, DLY3208, SREW and SSER. The data spans from 1915 to 2020. 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. A large proportion of the UK raingauge observing network (associated with WAHRAIN, WADRAIN and WAMRAIN for hourly, daily and monthly rainfall measurements respectively) is operated by other agencies beyond the Met Office, and are consequently currently excluded from the Midas-open dataset.

本英国小时降雨数据集包含指定时刻结束的单小时（或多小时）时段内的降雨量，以及倾斗式虹吸雨量计（tilting syphon gauges）记录的降雨持续时长。数据集同时涵盖降水量数据，但不存储24小时时段的累计降水量。本数据集在不同观测周期内先后使用过多种雨量计，详细信息请参阅关联的MIDAS用户指南。本版本替代了该数据集的过往版本，存档与本记录的关联文档中均提供了更新日志，用以说明本版本与过往版本间的差异。更新日志详细列明了新增、替换及移除的数据条目。本数据集由英国气象局（Met Office）在英国全境运营的观测站采集，数据通过以下报文类型传输：NCM、AWSHRLY、DLY3208、SREW及SSER。数据集的时间跨度为1915年至2020年。本数据集属于英国气象局依据《英国开放政府许可》（UK Open Government Licence）发布的Midas-open数据集合集（Midas-open dataset collection），仅包含英国气象局所有或运营的英国本土陆地表面观测数据。本数据集是内容更为完整但受访问限制的英国气象局综合数据存档系统（Met Office Integrated Data Archive System，缩写MIDAS）陆地与海洋表面观测站数据集的子集，该数据集同样可通过环境数据分析中心（Centre for Environmental Data Analysis）获取，详细信息请参阅本记录的关联数据集板块。英国多数雨量观测网络（分别对应小时、日、月降雨量测量的WAHRAIN、WADRAIN及WAMRAIN项目）由英国气象局以外的其他机构运营，因此目前未被纳入Midas-open数据集。
