    The Randolph Glacier Inventory (RGI) is a global set of glacier outlines intended as a snapshot of the world’s glaciers outside of ice sheets. It provides a single outline for each glacier from approximately the year 2000, as well as a set of attributes and other relevant auxiliary information. Glacier outlines are distributed as Shapefiles. Hypsometric data and attributes (CSV files) and metadata (json) are also available. All RGI data are packaged both globally and by region (as defined by the Global Terrestrial Network for Glaciers (GTN-G) Glacier Regions). The RGI is not suitable for measuring glacier-by-glacier rates of area change. However, it can be used to estimate glacier volumes; rates of elevation change at regional and global scales; and glacier responses to climatic forcing. RGI version 7.0 was developed by the “Working Group on the Randolph Glacier Inventory (RGI) and its role in future glacier monitoring” of the International Association of Cryospheric Sciences (IACS). The glaciological community contributes glacier mapping data to the Global Land Ice Measurements from Space (GLIMS) database. A subset of the glacier outlines in GLIMS are then extracted and reprocessed to produce the RGI. See the RGI documentation under "User Guide" (below) for more information.

    Le visualiseur des PEID fournit des informations sur les eaux souterraines dans les Petits États Insulaires en Développement. Actuellement, le système contient principalement des données issues du Programme d'Évaluation des Eaux Transfrontalières (TWAP) sur 43 PEID. Ces données comprennent des indicateurs décrivant les dimensions hydrogéologiques, environnementales, socio-économiques et de gouvernance des systèmes d’eaux souterraines des PEID.

    Les données ont été recueillies à partir d'enquêtes par questionnaire et d'une étude approfondie réalisée par l'Université Simon Fraser (Canada) et coordonnée par l'UNESCO-IHP. Les informations du système peuvent être explorées et analysées grâce à un visualiseur cartographique, particulièrement utile pour effectuer des analyses comparatives entre plusieurs PEID. De plus, des fiches d'information sur les PEID sont également disponibles, offrant des aperçus clairs pour chaque PEID. Des données supplémentaires seront collectées et intégrées au visualiseur des PEID au fur et à mesure de leur disponibilité.

    Pour toute question ou commentaire sur les données et informations des PEID, veuillez consulter notre page de l’Espace Focal PEID (https://www.un-igrac.org/areas-expertise/small-island-developing-states-sids)

    The Reference Observatory of Basins for INternational hydrological climate change detection (ROBIN) project established a new long-term collaboration of international experts to establish and sustain a global reference hydrological network (RHN), through common standards, protocols, indicators, and data infrastructure. ‘Reference Hydrometric Networks’ (RHNs), consist of gauging stations whose catchments are relatively undisturbed and record high quality data and little missing data. The concept of RHNs, their history and evolution are described in (Whitfield et al., 2012) previously and many countries have already established RHNs, however this is the first initiative to bring them together at a global level. The ROBIN Full Dataset consists of 3,060 stations in 30 countries, however the dataset described here is the ROBIN Public Dataset which contains metadata records for all 3,060 stations and daily streamflow data for a total of 2,386 stations. This tiered approached was due to data sharing restrictions in some countries. More information about the ROBIN Network and dataset can be found on the project website: https://www.ceh.ac.uk/our-science/projects/robin
