Short description

The C3S European Tourism "Mountain Tourism Meteorological and Snow Indicators" dataset provides pan-European information relevant to snow reliability, hence operating conditions of winter ski resorts under past and future climate conditions. It consists of 39 indicators characterizing atmospheric and snow conditions, with and without snow management (grooming, snowmaking), computed in a similar manner for all mountain regions in Europe at the scale of NUTS-3 regions and by steps of 100 m elevation on flat terrain. The 39 indicators are grouped in the following 7 groups: PR=precipitation indicators, Tas=temperature indicators, SD=snow depth indicators, SWE=snow water equivalent indicators, MM-PROD=amount of snow produced, WBT: wet bulb temperature-based indicators, BS-ES: beginning and end of season indicators. Past climate conditions based on reanalysis data span the period from 1961 to 2015, and future climate
conditions are based on an ensemble of adjusted climate projections spanning the period from 1950 to 2100, with 2006-2100 covered by RCP2.6 (2 GCM/RCM pairs) and RCP4.5 and RCP8.5 (9 GCM/RCM pairs each). This makes it possible to compute not only mean values of indicators for future time periods (2021-2040, 2061-2080 and 2081-2100) but also the multi-model standard deviation and quantiles of annual values (Q10, Q20, Q50, Q80 and Q90), which are critical for the assessment of snow reliability of mountain regions in a multi-annual perspective. The files are provided in NetCDF format.
