The ENSEMBLES downscaling portal. Beyond the ENSEMBLES project

The ENSEMBLES Downscaling Portal (http://www.meteo.unican.es/ensembles) was developed within the EU-funded ENSEMBLES project (2004-2009) to fill the gap between the coarse-resolution global model outputs and the high-resolution needs of end users, providing a Web-based user-friendly tool for calibration/downscaling. For this purpose, the portal includes data (common predictors such as SLP or Q850) from the ENSEMBLES project (global outputs from the Stream1 and 2 GCM simulations) and a number of popular statistical downscaling techniques (regression, GLMs, analogs, weather types, etc.), and allows performing downscaling using public observation datasets (GHCN, GSOD, etc.) and/or private observed data. Moreover, the portal is based on WEB and GRID technologies, allowing scalability though the transparent use of distributed resources.
A complete reimplementation of the portal (version 2) has been performed in 2011 to allow the development of new functionalities demanded by the supporting projects (METAFOR, FUME, QWeCI, MOSAICC, etc.): Metadata management, calibration of regional climate models, on-demand output formats, etc. Most of these functionalities will be also open to the public in the near future due to the public character of the supporting projects. For instance, we are working to include in the portal is the metadata query services developed within the METAFOR project, so users can query and search global simulation from CMIP5. Moreover the portal can now be embedded in a more general framework, in combination/cascade with other applications, using different style sheets to adapt to the required visualization style. For instance, the downscaling portal is part of the MOSAICC (MOdelling System for Agricultural Impacts of Climate Change, http://www.fao.org/climatechange/mosaicc) tool, developed by FAO to carry out each step of the impact assessment from climate scenarios downscaling to economic impact analysis at national level. In this case, the downscaling portal has been embedded in a common framework with a hydrological model (for estimating water resources for irrigation), a crop growth model (to simulate future crop yields) and finally a CGE (Computable General Equilibrium) model to assess the effect of changing yields on national economies.

In this presentation we describe the new functionalities and possibilities of the ENSEMBLES downscaling portal, which can now be easily adapted to new projects/institutions for particular requirements.
