Summary
A daily basis precipitation-sampling network for water isotope analysis (D and 18O) in Asia was launched by IORGC/JAMSTEC in 2002.
The number of station has gradually increased, and there are now more than 22 stations from the Maritime Continent to Siberia. Besides, river water sampling is being done at several stations along the big river (Ob, Enisei, and Lena river etc.) in every month. Detail see Readme_Isotope.txt
