    3 The User Data Gateway (UDG) is the one stop shop for climate data access maintained by the [http://www.meteo.unican.es Santander MetGroup]. The UDG builds on the
    4 [http://meteo.unican.es/udg-tap THREDDS Access Portal] (UDG-TAP) which is the entry point for authentication and data access (information for [wiki:./registration registration]).
     3The User Data Gateway (UDG) is the one-stop shop for climate data access maintained by the [http://www.meteo.unican.es Santander MetGroup]. The UDG builds on a THREDDS server with two extra layers for 1) authentication and 2) data access (based on R). The authentication builds on the
     4[http://meteo.unican.es/udg-tap THREDDS Access Portal] (UDG-TAP), which is the entry point to the UDG (information for [wiki:./registration registration]).

    66'''Authorization''' is organized in thematic groups, according to the data policies of different projects and international initiatives. Each group provides access to a particular catalog of datasets:
    77* '''PUBLIC_DATA''' (open). Includes data from publicly available datasets: observations (WFDEI), reanalysis (NCEP reanalysis1), seasonal re-forecasts (CFS_v2). [http://meteo.unican.es/ecoms-udg/dataserver/catalog Variables].
    8 * '''SPECS''', '''EUPORIAS''' and '''NACLIM''' (restricted to members of the above ECOMS projects). Provide access to private seasonal re-forecasts (System4) and reanalysis (ERA-Interim, JRA-55). [http://meteo.unican.es/ecoms-udg/dataserver/catalog Variables].
     8* '''SPECS''', '''EUPORIAS''' and '''NACLIM''' (restricted to members of the above ECOMS projects). A thematic group dealing with seasonal forecasting. Provides access to private seasonal hindcasts (System4, GloSea5, SMHI-EC-EARTH Euporias), as well as some other observational and reanalysis data used in these initiatives. [http://meteo.unican.es/ecoms-udg/dataserver/catalog Variables].
    99* '''VALUE''' and '''CORDEX-ESD''' (restricted to project members). Provide access to a subset of standard statistical downscaling predictors for reanalysis (ERA-Interim, JRA-55) and CMIP5 GCMs for different scenarios (historical, RCP4.5, RCP8.5). [http://meteo.unican.es/trac/wiki/udg/esd Variables].
    1010* '''ESGF-CORDEX'''. Interim group for accessing CORDEX datasets during [https://verc.enes.org/community/announcements/news/esgf-data-nodes-down ESGF shutdown].
    1111
    1212'''Data access''' is facilitated in two different ways:
    13 * '''Downloading''' subsets of the data (for a particular region and time period) from the UDG-TAP building on the OPeNDAP and subsection services from a THREDDS Data Server ([http://meteo.unican.es/udg-tds UDG-TDS catalog]).
    14 * '''Connecting remotely''' to the UDG-TDS from R and Matlab via  [wiki:./interfaces user-friendly interfaces].
     13* '''Downloading locally''' subsets of the data (for a particular region and time period) from the UDG-TAP building on OPeNDAP and subsetting services.
     14* '''Accessing remotely''' to user defined subsets via the loadeR R bundle.
