Short summary

We present 462 paired measurements of stable oxygen and hydrogen isotopes in monthly precipitation from 15 sites on Jeju Island, South Korea, collected between 2000 and 2003. Isotope values were generally lower in summer and decreased with elevation. Published with weather data and sampling information, this historical dataset provides a baseline for future monitoring and supports research on groundwater recharge and the island’s water cycle.
