HydroSOS: a pilot global Hydrological Status and Outlook System integrating national to global scale hydrological services for increased resilience to hydro-climatic risks
<p>Consistent hydrological status and outlook information across transboundary basins or regions of shared hydrological interest are not often available. Furthermore, whilst large-scale modelling capabilities are continually improving, there is an information and confidence gap between locally informed hydrological status information products and those developed globally.</p><p>HydroSOS is World Meteorological Organisation initiative that aims to increase global resilience to hydro-climatic risks through the production of hydrological status and outlooks assessments at different scales around the world. Currently in a pilot phase, HydroSOS is being developed through a collaboration between National Hydrometeorological Services, transboundary basin organisations, global modelling centres and the research community. The system will provide an appraisal of where current hydrological status is different from &#8220;normal&#8221;, as well as sub-seasonal to seasonal outlooks indicating whether this is likely to get better or worse over the coming weeks and months.</p><p>The HydroSOS programme consists of five main activity streams:</p><ol><li>Increasing the interoperability of hydrological status and outlook products through <strong>Common Technical Specifications.</strong></li> <li>Increasing national capabilities to generate hydrological status and sub-seasonal to seasonal outlook products through <strong>Guidance on Methods and Tools.</strong></li> <li>Increasing the utility of large-scale hydrological status and outlook modelling through <strong>Co-design of Global Products</strong>, with international partners working from local to global scale.</li> <li>Increasing shared production of transboundary hydrological status and outlook products through <strong>Regional Pilots</strong>, initially in South Asia and the Lake Victoria Basin.</li> <li>Integration of hydrological status and outlook products for national, regional and global users through a <strong>Demonstration Portal.</strong></li> </ol><p>This PICO contribution will present progress in the pilot project to date, including a hands-on demonstration of the web portal.</p>
