The new IAEA WISER (Water Isotope System for Data Analysis, Visualization and Electronic Retrieval) data portal for accessing GNIP (Global Network for Isotopes in Precipitation) and GNIR (Global Network for Isotopes in Rivers) data has been launched this week and is now accessible through NUCLEUS. This activity is related to a key component of the IAEA’s Isotope Hydrology Section mandate, as it deals with global isotope data compilation and dissemination. More than 4000 users had already registered in the old platform used to disseminate these data sets and thanks to the new features offered by this updated version of the portal, located at https://nucleus.iaea.org/wiser, easy data access and interpretation will be facilitated.

New features of the portal include more interactive elements for example graphical, global, map-based queries, point and click on a map, or drag across a map area. It is also possible to choose data timeframes and isotopes, or average them by month or by year. New climate data diagrams (precipitation, temperature, monthly summaries) and other calculated parameters are now also available as well as graphical display of station isotope data, including ordinary least squares (OLS), reduced major axis (RMA), and precipitation amount weighted OLS regressions (PWLSR), plus a display of core statistical parameters.

GNIP in WISER currently contains over 130,000 records, and stable isotopes are current to the end of 2013. They will be updated as verified data comes in. Tritium data after 2009 will also be updated in the next year. Further information about WISER sign-up and the data holdings can be found at the growing WISER FAQ.
