The standard deviation of total snowfall. Note that snowfall for an hourly period is typically derived from estimates that are substantially less reliable than actual observations typical for other data types.

When used in the context of climatology, snowfall is the typical value when there is snowfall (excluding periods without snowfall).

Total snowfall is not total snow depth. Total snowfall is only new snowfall for the time period.
