Sažetak
The stable isotopic composition of hydrogen and oxygen (delta2H and delta18O) and tritium activity are monitored in monthly precipitation at Ljubljana since 1981. Seasonal variations of delta2H and delta18O are observed and are typical for continental stations of the Northern Hemisphere. The weighted mean delta delta2H and delta18O values are -59%o and -8.6%o, respectively. The orthogonal Local Meteoric Water Line is delta2H = (8.06 +- 0.08) delta18O + (9.84 +- 0.71), and the temperature coefficient of delta18O is 0.29%o/oC. Deuterium excess weighted mean value is 9.5%o and indicates the prevailing influence of the Atlantic air masses. Tritium activity in monthly precipitation shows also seasonal variations which are superposed to the decreasing trend of mean annual activity. In the paper overview of the measurements and statistical analyses are given for complete set of numerical data for the period 1981 – 2006.
