Description

Metadata

The isotopic compositions of daily precipitation were measured at two stations, Yadong and Pali, in the central Himalayas. The precision for δ18O and δD is ±0.1‰ and ±0.4‰, respectively. The meteorological data, including the collection of precipitation amounts and surface air temperature, was obtained by the Institute of Tibetan Plateau Research, Chinese Academy of Sciences, China.
