沼口様：
CC:GAME-jp の同位体水循環に関心のある方々へ：
以下のように、IAEAが気候・水循環（モデル）研究に関するワーキンググループ設立
および
そのためのワークショップを今年の８月末ー１１月にかけて、行うようです。
関心のある方は、IAEAの Dr. Gibsonに問い合わせてください。
（少なくとも、沼口さんはぜひコミットされることを期待します。）

>Hi Ron,
>There is a great interest in expanding IAEA's contribution to "climate"
>studies, as part of the recent transition of Hydrology from a
>sub-programme
>to a full programme of IAEA. Our major initiatives to date are in the
>areas
>of tracing GHG's and isotopes in precipitation. To further support
>climate
>studies we have also initiated a series of working groups to address key
>issues in the water and climate research community. These include:
>
>-Isotopes in Water Cycle Models (IWCM), 27-29 August 2001, Vienna,
>Austria
>-Isotope Indicators of Sustainability in Hydrologic Systems (DH2O),
>15-17
>October 2001, Vienna Austria
>-Isotopes in Integrated (Carbon and Water) Climate System Studies
>(ICSYS),
>18-20 November 2001, Vienna Austria
>
>As I mentioned, we are also designing a river programme. This is an
>obvious
>extension of the isotopes in precipitation programme. Measuring stable
>isotopes of water in discharge can provide contraints on AGCM and
>hydrological models, a primary objective of GEWEX. As part of the river
>initiative we intend to coordinate and fund a 3- to 5-year project on
>isotope mass balance of river basins involving about 10 or 15
>scientists.
>First of all, we would like to know if there are existing GEWEX projects
>which use isotope mass balance. If so, we would like to include these
>people
>and their data in our project.
>
>What is really lacking in terms of data are good river discharge isotope
>measurements in relevant locations (But perhaps there are GEWEX studies
>we
>are not aware of?). We would like to initiate a "pilot" study aimed at
>demonstrating isotope mass balance in a few basins, which would require
>a
>modest river sampling programme. Can you recommend where we should be
>working to support GEWEX? These pilot studies will hopefully provide
>support and justification for a global network of isotopes in river
>discharge, linked to the IAEA/WMO Global Network for Isotopes in
>Precipitation. We hope that this programme is of interest to GEWEX and
>that
>we might be able to facilitate and cooperatively enhance the
>isotope-based
>work.

>If you are interested, perhaps we could invite you to Vienna to discuss
>the
>possibilities? We also welcome GEWEX involvement in the working groups
>mentioned above. I can send more information on these if you like.
