Snow Water Equivalent (SWE) is modeled statistically depending on snow depth, altitude, date and region in Switzerland.


swe.jo09(data, alt, region.jo09)



A data.frame of daily observations with two columns named date and hs referring to day and snow depth at that day. The date column must be a character string with the format YYYY-MM-DD. The hs column must be snow depth values ≥ 0 in m.


station elevation in meters


Integer number of the Swiss region where the station belongs to, according to Fig. 1 in the original reference. Must be one of 1,2,3,4,5,6,7.


swe.jo09 This model parametrizes bulk snow density using snow depth, season (i.e. month), site altitude and site location. The location is implemented by a density offset according to the region in Switzerland, where the station belongs to. Non computable values are returned as NA.
