Environmental isotope data of the Tibetan Plateau (2005-2009)


This dataset contains the precipitation (P), river water (R) and lake water (L) isotope records for Lhasa and the Yamdrog Yumtso basin (including Yamdrog Yumtso 90°08′ E - 91°45′ E, 28°27′ N - 29°12′ N, 4440 m, and Pumayum Co 90°13′ E - 90°33′ E, 28°29′ N - 28°38′ N, 5030 m) and the Nam Co Basin (90°16′ E - 91°03′ E, 30°30′ N - at 30°56′ N, 4718 m) on the Tibetan Plateau. It can be used for studies on stable isotope observations of precipitation, river water and lake water in typical areas of the plateau.

The precipitation, river and lake water samples are collected in selected typical areas, and the values of stable isotopes are measured by a gas stable isotope ratio mass spectrometer (MAT-253-IRMS) after sealed storage. A data sheet is entered by a specific person based on the measurement results. The data in this dataset are from observations and measurements obtained in strict accordance with the sample collection specifications and have been published in relevant academic journals; the stable isotope of all samples is measured using the MAT-253 gas mass spectrometer at the Key Laboratory of Environment Changes and Land Surface Processes of the Institute of Tibetan Plateau Research, Chinese Academy of Sciences. Samples are cryopreserved before measurement. The measurement results are the part per thousand deviations from V-SMOW; some obvious error data are eliminated when processing to generate the data table.
