This dataset provides high-resolution (1km x 1km), daily reconstructions of temperature and precipitation fields for Switzerland from 1763 to 2020. The fields are reconstructed using the analog resampling method and subsequent data assimilation for temperature and quantile mapping for precipitation. The dataset consists of two subperiod: (1) an update of the reconstructions provided by Pfister (2019) (doi:10.1594/PANGAEA.907579) for the period 1864 to 2020 with the higher resolution grid and extending to 2020, and (2) a new reconstruction for the period 1763 to 1863 for which so far no reconstruction existed. The dataset for 1864 to 2020 is reconstructed based on observational data from the Swiss meteorological service with a high quality and dense station network. The reconstruction for the early period from 1763 to 1863, is based on early instrumental measurements of temperature, pressure, precipitation, and precipitation occurrence that have been rescued in various projects. Observations entering the reconstruction for the early period are much more scarce and their quality is lower. We recommend to notice this when using the reconstructions. For further information about the dataset, please refer to the Imfeld et al. (in review).
