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.

Short summary
We provide the only known long temperature and pressure instrumental record for the south-eastern Alps covering the first half of the 19th century. It was measured in the town of Rovereto, in the Adige valley, between 1800–1839 by a physics teacher. The data are complemented with measurements from Bolzano/Bozen for 1842–1849 and are converted to modern units and homogenized to account for changes in observation times and exposure of the instruments.
