Sažetak
The stable isotopic composition of hydrogen and oxygen (δ 2H and δ 18O) and tritium activity (3H) are monitored in monthly precipitation at Ljubljana since 1981. Here we present complete set of numerical data and the statistical analysis for period 1981 – 2006. Seasonal variations of δ 2H and δ18O are observed and are typical for continental stations of the Northern Hemisphere. The weighted mean δ2H and δ18O values are -59‰ and -8.6‰ , respectively. The orthogonal Local Meteoric Water Line is δ 2H = (8.06 ± 0.08)δ 18O + (9.84 ± 0.71), and the temperature coefficient of d18O is 0.29‰ /º C. Deuterium excess weighted mean value is 9.5‰ 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.
