Tritium and stable isotope variations in precipitation of Croatia and Slovenia

Within the IAEA Co-ordinated Research Program "Isotopic Composition of Precipitation in the Mediterranean Basin in Relation to Air Circulation Patterns and Climate" the network has been extended to several stations along the Adriatic coasts of Croatia and Slovenia in the period between September 2000 and December 2003: Portorož-Airport (2 m a.s.l., 13.1°C, 911 mm) and Kozina (497 m a.s.l., 1511 mm) in Slovenia, and in Croatia Malinska on Krk Island (1 m a.s.l., 14.8°C, 1306 mm), Zadar (5 m a.s.l., 15.9°C, 937 mm), Komiža on Vis Island (6 m a.s.l., 17.6°C, 706 mm), Dubrovnik (52 m a.s.l., 17.2°C, 1092 mm), and Zavižan on Mt. Velebit (1594 m a.s.l, 4.3°C, 2113 mm/year). The sampling sites are characterized by different types of climate (continental and Mediterranean, or mixing influence) and the corresponding mean monthly temperatures and mean yearly precipitation amounts for the same period are given above in parentheses. The lowest mean temperature and highest amount of precipitation were recorded at Zavižan. Marine stations at southern Adriatic show higher mean temperatures than the continental stations, while at the North Adriatic mean temperature lies between the continental and marine values. The presented data shows present-day temporal and spatial distribution of tritium and stable isotopes 2H and 18O in precipitation of a relatively small area rich in climatic diversity. The data can be used in various applications, such as climatology and hydrology.
