EURO-CORDEX ensemble of annual snow-water-equivalent and number of snowday

To calculate the annual mean cdo was used. The annual snow water equivalent is aggregated to annual mean, where the year starts in September and ends in August. The number of snow days are calculated according to the definition : a snow day is defined as 3 cm of snow. We used snw (snow water equivalent), which most RCMs provided. snowday: snw >= 9.36 [kg/m²]; snd >= 0.03 [m] (snw = 0.03 m *0.312 kg/m3) If snw for the RCM was not provided, we used snd (snow depth) and coverted it to snw by mulipying it with the desity of 0.312 kg/m³
