Abstract. Central Europe is among the regions with the largest availability of pre-industrial meteorological records. In the Alps, however, such records are relatively rare, especially in the southern slope. We recently found and digitized two new pressure and temperature series for the Alpine cities of Rovereto (1800–1839) and Bolzano/Bozen (1842–1849) covering together the first half of the 19th century, a period characterized by large climate variability and important extreme events. The meteorological record of Rovereto, in particular, is the oldest available for the southeastern Alps. We used the shorter record of Bolzano/Bozen as a testbed for different digitization methods, namely citizen science and machine-learning based Optical Character Recognition. The data are converted to modern units, quality controlled, and homogenized. We also provide daily and monthly means together with an estimation of their uncertainty.

南欧阿尔卑斯山的两个新的早期气压和温度仪器记录

摘要。中欧是拥有最多工业化前气象记录的地区之一。然而，在阿尔卑斯山，这样的记录相对较少，尤其是在南坡。我们最近发现并数字化了阿尔卑斯山城市罗韦雷托 (1800-1839) 和博尔扎诺/博曾 (1842-1849) 的两个新的压力和温度系列，涵盖了 19 世纪上半叶，这一时期的特点是气候多变和重要极端事件。尤其是罗韦雷托的气象记录，是阿尔卑斯山东南部可用的最古老的气象记录。我们使用 Bolzano/Bozen 的较短记录作为不同数字化方法的测试平台，即基于公民科学和机器学习的光学字符识别。数据被转换为现代单位、质量控制和均质化。
