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).
