ABSTRACT:
This dataset presents a georeferenced stable isotope record of rainwater from Morelos, Mexico, comprising 121 samples collected between 2016 and 2022. The dataset includes measurements of δ¹⁸O, δ²H, and d-excess, together with sampling dates and geographic coordinates. Rainwater samples were collected using RS2 PALMEX collectors installed at six monitoring sites: Tezoyuca (1,194 m asl), Temixco (1,264 m asl), Cuernavaca (1,638 m asl), Huitzilac (2,600 m asl), Tres Marías (2,813 m asl), and Tres Cumbres (3,290 m asl). These sampling stations are part of the National Network of Isotopes in Precipitation, operated by the Department of Hydrology of the Mexican Institute of Water Technology (IMTA). The dataset provides spatially distributed observations of stable water isotopes across an elevation gradient and supports applications in hydrology, hydrogeology, ecohydrology, isotope hydrology, and water-resource management. It also contributes to improving the availability of stable isotope precipitation data for central Mexico and provides a reference dataset for investigating precipitation processes, moisture sources, and groundwater recharge.
