Stable isotope composition of daily and monthly precipitation in Zagreb

In the frame of the IAEA Research Contract Tritium and stable isotope distribution in the atmosphere at the coastal region of Croatia we determined isotope composition of monthly precipitation (3H activity, delta 2H, delta 18O) during the three-year period (2001-2003) at six stations (4 maritime and 2 continental) in Croatia (Horvatinčić et al, 2005). The aim was to determine natural variations of radioactive isotope 3H, as well as distribution of stable isotopes in precipitation over a relatively small area with different climatic and geographical characteristics. In this investigation we also included the stable isotope measurements of daily precipitation collected at one of the continental station, Zagreb, for the period October 1, 2002 to April 1, 2003. These isotopic data of individual precipitation can give us more information of individual mass trajectories, e.g., more information on the source of the atmospheric moisture during particular events.
