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.
