Water Stable Isotopes and d-excess Compositions of Precipitation Dataset in Guyuan Station

A field precipitation observation station
(Guyuan Station) was set in Guyuan, China (36°00′16″N, 106°17′07″E) and 66 event-based
precipitation samples from June 2018 to August 2020 were collected immediately
after each precipitation event. Through indoor experimental analysis of
precipitation samples, a dataset of stable isotopes of hydrogen and oxygen and
deuterium excess compositions of precipitation in Guyuan Station was obtained.
The dataset includes stable isotopes (δ²H
and δ¹⁸O) and deuterium excess (d-excess) compositions of
precipitation in Guyuan Station.

在中国固原（地理坐标：36°00′16″N，106°17′07″E）布设了野外降水观测站——固原站。2018年6月至2020年8月期间，于每场降水事件结束后即刻采集了66份事件型降水样本。通过对降水样本开展室内实验分析，构建得到固原站降水的氢、氧稳定同位素及氘盈余（deuterium excess）组成数据集。该数据集涵盖固原站降水的氢稳定同位素（δ²H）、氧稳定同位素（δ¹⁸O）及氘盈余（d-excess）组成数据。
