[English] Workshop on Integrated Development of Water Isotope ISOSCAPE: Bridging Observations, Models, and Data Assimilation

• Date: September 7, 2026 (Mon) 12:00 – September 8, 2026 (Tue) 17:00

• Venue: Kashiwa Campus, Chiba University, Japan

• Presentation format: On-site only (oral or poster)

• Language: English is preferred. Students may present in Japanese, but slides should be in English.

• Registration form: https://forms.gle/zqXC9M8GGcsPp7r47

• Registration deadline: July 31, 2026

This workshop aims to foster a research community for advancing hydrological cycle science using water isotopes. Researchers working on observations, numerical modeling, data assimilation, paleoclimate reconstruction, and related topics are welcome. Through the integration of various water isotope observations and model evaluations, we seek to establish a reliable framework for estimating water isotope distributions from regional to global scales.

Students are especially encouraged to participate and present their work. Limited travel support is available for selected students and early-career researchers.

Both oral and poster presentations are welcome.
