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.
