Hydro-CH2018 datasets

A selection of datasets from the Hydro-CH2018 hydrologic scenarios is available for use in climate impact research and practice.

Terms and Conditions

The Hydro-CH2018 scenario data are provided under the CC BY 4.0 license.

Among others, this means that users are allowed to share (copy and redistribute) and adapt (remix, transform, and build upon for any purpose, even commercially) the data, under the condition that proper reference is given to the Hydro-CH2018 datasets. Please note also that all material is provided without any warranties and guarantees.

Station and site data

The datasets contain modeled mean runoff changes (absolute and relative) for different emission scenarios and different time horizons at monthly, seasonal, and annual resolution at selected stations or sites:

Data set L01: Runoff from mesoscale catchments at selected stations.

Changes in mean monthly, seasonal, and annual runoff for three emission scenarios (RCP2.6, RCP4.5, and RCP8.5) for three future time periods: 2035 (2020-2049), 2060 (2045-2074), and 2085 (2070-2099). The focus of this dataset is on mesoscale catchments (10-1700 km2).

Data set L02: Runoff from macroscale catchments at selected stations.

Changes in mean monthly, seasonal, and annual runoff for three emission scenarios (RCP2.6, RCP4.5, and RCP8.5) for three future time periods: 2035 (2020-2049), 2060 (2045-2074), and 2085 (2070-2099). The focus of this dataset is on macroscale catchments (>1000 km2).

Data set L03: Runoff from glaciated headwater catchments at selected sites

Changes in mean monthly, seasonal, and annual runoff for three emission scenarios (RCP2.6, RCP4.5, and RCP8.5) for three future time periods: 2035 (2020-2049), 2060 (2045-2074), and 2085 (2070-2099). The data set focuses on snow and glacier ice melt.

Raster data

The maps compiled in this dataset contain gridded (500mx500m) mean monthly and annual discharges for three emission scenarios (RCP 2.6, RCP4.5, and RCP8.5). The maps are available for three time horizons in the future: 2035 (2020-2049), 2060 (2045-2074), and 2085 (2070-2099). In addition, the maps for the reference period (1981-2010) and the results of the control run are also included. The files are available as ASCII grids, without lakes with reference system CH1903_LV95.
