Stable isotopic compositions (delta2H and delta18O) of daily precipitation collected in the period from October 2002 to March 2003 and monthly precipitation in the period from 2001 to 2003, as well as the corresponding meteorological data (temperature, amount of precipitation), all collected in Zagreb, Croatia, are presented. delta2H and delta18O values, both daily and monthly, show large variations due to large temperature variations and the different origin of the air masses. Variations are larger for daily samples than for composite monthly samples. Good correlation of delta18O with temperature is obtained for both types of samples. On the basis of the correlation between delta2H and delta18O, the local meteoric water line is close to the global meteoric water line. Deuterium excess of both daily and monthly precipitation indicates that in the Zagreb area, the influence of air masses from the Mediterranean area prevails in the autumn period.
呈现了2002年10月至2003年3月期间在克罗地亚萨格勒布收集的日降水量以及2001年至2003年期间月降水量的稳定同位素组成（δ²H和δ¹⁸O），以及相应的气象数据（温度、降水量）。由于温度变化大和气团来源不同，日降水量和月降水量的δ²H和δ¹⁸O值均呈现出较大变化。日样本的变化比综合月样本的变化更大。两种类型的样本中，δ¹⁸O与温度均具有良好的相关性。基于δ²H和δ¹⁸O之间的相关性，当地大气降水线接近全球大气降水线。日降水量和月降水量的氘过剩表明，在萨格勒布地区，秋季来自地中海地区气团的影响占主导。
