The User Data Gateway (UDG)

The User Data Gateway (UDG) is the main access point to the different data services provided by the ​Santander Meteorology group. The UDG builds on a a THREDDS Data Server, UDG-TDS) and on a web portal for user authorization (the THREDDS Administration Portal, UDG-TAP). In addition to the standard web interface to explore and download the datasets, the UDG includes different (R and Matlab) packages for accessing remotely subsets of the data. A schematic view of the UDG is provided in the figure below.

The UDG supports the following international activities: <ul> <li>The group <B>PULIC_DATA</B> offers a number of datasets which are in the public domain (e.g. WATCH data, NCEP reanalysis, NCEP CFSv2 seasonal forecasting hindcast). <li><B>​EUPORIAS</Ba>, <B>​SPECS</B> and <B>​NACLIM</B> (the European coordination of climate services activities ​ECOMS consortium). Global seasonal forecasting datasets from state-of-the-art seasonal forecasting systems (e.g. ECWMF System4). More info ​here. <li><B>​VALUE</B> and <B>​CORDEX-ESD</B>. A reduced set of global post-processed predictors from ERA-Interim for statistical downscaling purposes (work in progress to include hires observational gridded datasets over different european regions). More info ​here. </ul> The use of UDG requires ​registration. Access to data is obtained after requesting membership to the different groups. The data in the PUBLIC_DATA group is freely available to anyone (automatic membership authorization upon request). The data for particular groups/projects requires membership to the particular projects (moderated membership authorization). Besides the web services for subset data downloading, different R and Matlab packages have been developed to remotely access the different datasets. <ul> <li> The ECOMS data access R and Matlab packages allow accessing seasonal forecast data using a single command (see an example here). <li> The ​downscaleR package allows accessing observational and reanalysis datasets using a single command. </ul>

The group also supports a node of the <b>Earth System Grid Federation (ESGF)</b> which builds on the UDG-TDS and provides EURO-CORDEX simulations using the WRF model. ​http://data.meteo.unican.es/

All these services build on the ​computing and storage infrastructure of the group.
