This article presents daily rainfall data and metadata for Ireland transcribed from historical manuscript and printed copies of rainfall registers located in Met Éireann's archives. To facilitate the transcription of rainfall observations from paper records, the historical manuscripts were scanned and integrated into Met Éireann's digital archives. The transcription from digital image to data format was undertaken in collaboration with students at Maynooth University as part of a novel crowdsourcing initiative to integrate data rescue activities into the classroom. In total, 3,616 station years of rainfall data (~1.32 million daily values) were transcribed. The data, which was double keyed, have undergone basic quality assurance to check for transcription errors and the resultant raw data and associated metadata are presented here. Ongoing work involves the application of further quality assurance and homogenization techniques to develop a long-term, quality assured daily rainfall network for Ireland.

爱尔兰 1940 年前的日降雨量记录

本文介绍了爱尔兰的每日降雨量数据和元数据，这些数据和元数据从历史手稿和位于 Met Éireann 档案中的降雨量登记册的印刷副本中转录而来。为了便于从纸质记录转录降雨观测，历史手稿被扫描并整合到 Met Éireann 的数字档案中。从数字图像到数据格式的转录是与梅努斯大学的学生合作进行的，作为将数据救援活动整合到课堂的新型众包计划的一部分。总共转录了 3,616 个站点年的降雨数据（约 132 万日值）。数据采用双键加密，经过基本质量保证以检查转录错误，此处提供了由此产生的原始数据和相关元数据。
