Two-year daily precipitation stable isotope dataset (δ¹⁸O and δ²H) from a continental station in NW Croatia.

ABSTRACT: The stable water isotopic composition (δ¹⁸O and δ²H) of daily precipitation from north-western Croatia (near Samobor town) is presented. The dataset includes a total of 288 precipitation samples collected from December 2022 to November 2024. The collection period roughly covered a 24-hour cycle, starting predominantly early in the morning. Stable hydrogen and oxygen isotope analyses of the samples were carried out using a Picarro L2130-i Isotope analyzer, with a precision of 1 ‰ for δ²H and 0.2 ‰ for δ¹⁸O. The raw isotopic data of the precipitation samples are presented in δ-notation (‰) normalized to the international standard VSMOW (Vienna Standard Mean Ocean Water). Additionally, the d-excess values for each sample and the Local meteoric water
