Future river water temperatures in Switzerland - SwissFuRiTe

The SwissFuRiTe dataset consist of daily water temperature simulations from 82 catchments in Switzerland, from 1990 to 2099, made with the climate change scenarios for Switzerland (CH2018) and the hydrologic scenarios (Hydro-CH2018). Temperature simulations were conducted with the air2stream and air2water models. The SwissFuRiTe.zip file contains water temperature simulations as well as model input data of air temperature and river discharge in three folders Water_Temp, Air_Temp and Flow. Note that the input data have been adjusted by the authors in this study. For original air temperature and flow data as well as additional information the reader is pointed towards the sources given below. Each individual file composes all available climate simulations (GCM-RCMs) used at that station. The filename gives the following information separated by “_”: MeteoSwiss meteorological station (ex. AIG) FOEN Hydrological station (ex. 2009) Emission scenario (ex. RCP8.5) Water temperature model (ex. air2stream) Hydrological model (ex. PREVAH-WSL) Physical parameter (ex.

Atmospheric temperature climate data from the CH2018 project was obtained from the Swiss National Centre for Climate Services (nccs.admin.ch) data portal. On the same portal, discharge datasets from the Hydro-CH2018 project are available but at a temporally limited scale (monthly, seasonally and yearly means). We required daily resolved discharge data which was obtained directly from Massimiliano Zappa (model M1), Daphné Freudiger (M3), and Adrien Michel (M4). Data from model M2 (Muelchi et al., 2021) is available at http://doi. org/10.5281/zenodo.3937485.
