We extended the Swiss daily climate reconstructions from 1763 to 2020 to six additional variables at 1 × 1 km resolution using analogue resampling and data assimilation. Wind and temperature reconstructions show reasonable skill, while humidity and sunshine duration perform less well. Application to historical wildfire events demonstrates the data set's potential for impact studies. This is the first Swiss data set providing several variables at a high-resolution of 1 × 1 km and going back to 1763.
