Climatic dataset for Switzerland downscaled from MeteoSwiss gridded data at 1km to 25m using local regressions. It provides up-to-date climatic data at a resolution of 25m for Switzerland that are compatible with the 5th assessment report of the IPCC (AR5; reference period 1981-2010). The dataset is derived from daily MeteoSwiss Grid-Data Products at 1km resolution for 1981-2017 (daily mean/max/min temperatures (TaveD/TminD/TmaxD), daily sum of precipitation (PrecD ), daily relative sunshine duration (SrelD)), and monthly potential incoming solar radiations (Srad) calculated at 25m for Switzerland by WSL. Transient daily time series of gridded climate scenarios of temperature and precipitations between 1981-2099 at 0.02°D (~2.2 km) from the CH2018 initiative used to calculate future climatic layers for 3 GCMs (HADGEM, ECEARTH, MPIESM, and IPSL), 3 time slices (2020-2049, 2045-2074, and 2070-2099) and 2 representative concentration pathways (RCP 4.5 and 8.5).
