Context
The High Snow Days index is relevant to the tourism and water sectors. This Index is part of the Snow and Land Ice Hazard type of the Snow and Ice category of the classification. A higher/lower index value indicates more/less days with high snow amounts and thus higher/lower accumulation of snow from snowfall precipitation.
Definition
The High Snow Days index (days) counts the number of days where the water equivalent of natural snow is above a given threshold (here 120 kg m-2) from august to july of the following year.
Data Sources
The data was assembled on behalf of the Copernicus Climate Change Service (C3S) based on reanalysis data hosted on the C3S Climate Data Store (CDS). The observed and simulated index data are from the Mountain tourism meteorological and snow indicators for Europe from 1950 to 2100 derived from reanalysis and climate projections dataset. The dataset is based on the UERRA reanalysis and a set of 9 bias-adjusted multi-model simulations from the EURO-CORDEX experiment. The index data simulations have an annual temporal resolution, a spatial resolution over NUTS3 regions, a vertical resolution of 100m and cover scenarios RCP4.5 and RCP8.5. More technical specifications can be found in the dataset documentation.
