Isotopic composition of Cyclone Mekunu rainfall in 2018, Southern Oman

Hydrogen and oxygen stable isotope analyses of precipitation sampled during Cyclone Mekunu. During Cyclone Mekunu rainfall samples were taken at three different stations in southern Oman. The results are expressed in per mil using the conventional delta-notation relative to Vienna Standard Mean Ocean Water (V-SMOW). More or less independent from the instrument, the 1s reproducibility is commonly better than ± 0.2 per mil (d18O) and ± 0.4 per mil (d2H).

本数据集包含气旋梅库努（Cyclone Mekunu）期间采集的降水样品的氢、氧稳定同位素分析结果。气旋梅库努期间，研究人员在阿曼南部的三个不同站点采集了降雨样品。所有分析结果均采用相对于维也纳标准平均海洋水（Vienna Standard Mean Ocean Water，V-SMOW）的常规δ记法，以千分比（‰）为单位表示。该分析的1σ重现性基本不受仪器影响，通常优于±0.2‰（δ¹⁸O）与±0.4‰（δ²H）。
