Sažetak
Tritium is an important natural tracer in hydrological sciences. The dataset used in the present study is compiled of ~7, 700 monthly precipitation tritium activity values from 71 stations, covering the period from Jan 1961 to Dec 2017. As a pre-processing step, a sequential univariate outlier detection procedure was applied in which the time series of the stations were pairwise compared for each year. Variogram analysis was then applied to the precipitation amount weighted annual averages of tritium activity. Variograms applicable for interpolation were obtained from years 1977, 1982, 2007, 2010, 2011 and 2012. These where further on used as the reference years, and their variograms were used as the weights for kriging in the intermediate years. It suggests a decrease in spatial representativity of the precipitation monitoring stations from 590 km in 1977 to ~270 km in 2012, which might reflect the diminishing influence of broadly homogenous anthropogenic disturbance (i.e., global effect of bomb tests) on natural tritium levels of precipitation. Since 3H activity in the region approximated the natural level in precipitation by the early-1990s, it can be expected that the ~270 km range obtained for the 2012 reflects the natural 3H variability. The final product of the research was a database of the interpolated 1x1 km grids of each year’s tritium activity.
