Geostatistical study of precipitation series in Austria: time and space

F. Holawe, R. Dutter
1999 Journal of Hydrology  
From the database of each station, we first calculated the most essential properties of the variogram in its general form, namely sill, range and nugget effect.  ...  For this study, the daily data from more than 400 precipitation stations in Austria recorded over a period of 20 years was used.  ...  In both directions, we find approximately the same sill, nugget effect and range. This means that the variable range is not really influenced by a distinct topographical structure.  ...
