[Parameter Line Entry] SnowUnitText=cm [Function] 
Set in Snow units box in the Display Configuration Screen General block. Default is cm. This allows you to set the text that appears with the snow depth in the weather diary. Note that there is no significance attached to this and the effect is purely cosmetic; the snow depth is effectively unitless and you can supply any text you wish, remember all snow depth observations must be entered as an integer (without any decimal part)!
