The European Climate Observations, Modelling and Services initiative ECOMS coordinates the activities of three ongoing European projects ([EUPORIAS](http://www.euporias.eu EUPORIAS), [SPECS](http://www.specs-fp7.eu SPECS) and [NACLIM](http://naclim.zmaw.de NACLIM)). Different sector-specific impact activities to be undertaken in these projects require a reduced number of variables (typically at surface, but also at pressure levels for downscaling purposes) from different data sources with different terms of use.
As part of the data management activities in these projects, the Santander Meteorology Group (UC-CSIC) has established the ECOMS User Data Gateway (ECOMS-UDG) to provide a centralized access point to collections of impact-relevant variables, gathered from existing state-of-the-art datasets. The ECOMS-UDG is composed of a catalogue of datasets and services provided by a THREDDS data server and a suite of tools for user-friendly data exploration, access and post-processing. For more information visit the ECOMS-UDG wiki!.
The ecomsUDG.Raccess is a R package envisaged as a R interface for accessing the hindcast datasets stored at the ECOMS-UDG. For more details on the R interface to the ECOMS-UDG follow this link.
