Stable isotope ratios of atmospheric water vapor in MR20-05C

Hourly stable water isotope data measured by isotope and gas concentration analyzer for atmospheric water vapor in the Arctic Ocean during the period from Septer to October 2020. The data set includes water vapor concentration, oxygen, hydrogen, and d-excess, averaged for the hourly time scale based on the raw data of 1-2 Hz frequency.本数据集涵盖2020年9月至10月期间，采用同位素与气体浓度分析仪对北冰洋大气水汽观测得到的逐小时稳定水同位素数据。数据集包含水汽浓度、氧同位素、氢同位素以及氘过量参数（d-excess），所有指标均基于1~2 Hz采样频率的原始观测数据，按小时时间尺度进行平均处理后得到。
