Camels Switzerland

We present CAMELS-CH (Catchment Attributes and MEteorology for Large-sample Studies – Switzerland), a large-scale hydro-meteorological dataset for Switzerland and its neighboring countries. Covering 331 catchments, about one-third of which extend into Austria, France, Germany, and Italy, the dataset captures the diverse landscapes of Switzerland, including mountains, karst regions, and cultivated areas. The catchments are influenced by various hydrological regimes, such as glacier-, snow-, or rain-dominated systems.

CAMELS-CH (Höge et al., 2023; available at doi.org/10.5281/zenodo.7784632) includes 40 years of data (1981–2020), featuring daily records of streamflow, water levels, precipitation, air temperature, and snow water equivalent data starting from 1998. Additionally, it provides annual land cover and glacier change data for each catchment. The static attributes cover topography, climate, hydrology, soils, geology, land use, and human impact. This dataset complements similar publicly available datasets, offering comprehensive data from Switzerland, often referred to as the "water tower of Europe."


Extensions to include hourly data and chemistry data are currently in progress.
