藏东南大气水汽稳定同位素观测数据重点记录了大气中水汽的稳定同位素δD和δ¹⁸O值，是研究该区域水循环、降水形成机制及气候变化过程的重要基础资料。数据主要来源于藏东南地区鲁朗站布设的野外观测站点（东经94°44'，北纬29°46'，海拔3326m），利用大气水汽稳定同位素观测设备进行高频率监测，计算原始实时观测数据的月均值；为保证数据质量，采用配套的校准系统定期校准仪器，确保数据的精度以及准确度。稳定同位素能指示水汽的蒸发源、冷凝过程及降水再循环等信息，是研究区域水汽来源及输送过程的重要手段。该数据结合气象要素如温度、湿度、气压、风速和降水量等，能反映水汽在大气中的传输路径、源区特征及其演变过程。

Atmospheric water vapor stable isotope observation data from southeastern Tibet focuses on recording the δD and δ¹⁸O values of stable isotopes in atmospheric water vapor, serving as critical foundational data for studying regional water cycles, precipitation formation mechanisms, and climate change processes. The data is mainly sourced from field observation stations established at the Lulang Station in southeastern Tibet (longitude 94°44'E, latitude 29°46'N, altitude 3326 m). High-frequency monitoring is carried out using dedicated atmospheric water vapor stable isotope observation equipment, and monthly averages of the raw real-time observation data are calculated. To ensure data quality, a supporting calibration system is used to regularly calibrate the instruments, thus guaranteeing the precision and accuracy of the dataset. Stable isotopes can provide insights into information such as water vapor evaporation sources, condensation processes, and precipitation recycling, acting as an important tool for studying regional water vapor sources and transport processes. When combined with meteorological elements including temperature, humidity, atmospheric pressure, wind speed, and precipitation, this dataset can reflect the transport paths, source region characteristics, and evolutionary processes of water vapor in the atmosphere.
