 v8 The different nature of the different climate products, models and variables, and the idiosyncratic naming and storage conventions often applied by the various modelling centres, makes necessary a previous homogeneization across datasets in order to implement a truly user-friendly toolbox for data access. The ecomsUDG.Raccess package achieves this aim by defining a common ''vocabulary'' to all climate datasets. The particular variables of each dataset are translated -and transformed if necessary- into the common vocabulary by means of a ''dictionary''. Both features are next described: The different nature of the different climate products, models and variables, and the idiosyncratic naming and storage conventions often applied by the various modelling centres, makes necessary a previous homogeneization across datasets in order to implement a truly user-friendly toolbox for data access.
