 v67 '''Data Homogeneization:''' The different nature of the datasets, and the idiosyncratic naming and storage conventions often applied by the modelling centres, makes necessary an homogenization across datasets in order to implement a truly user-friendly toolbox for data access.  To this aim, the [wiki:RPackage R package for data access] has been developed. Data homogenization is achieved through the creation of a common vocabulary. The particular variables of each dataset are then translated -and transformed if necessary- into the common vocabulary by means of a ''dictionary''. Both features -vocabulary and dictionary- are described [wiki:RPackage/Homogeneization here]. In particular, some typical transformations performed by the loadECOMS interface are deaccumulation of initialization-accumulated variables to daily accumulated (i.e.: '''DAr''' --> '''DA''') and scaling and/or offset of variables to match standard units (e.g. -273.15 for conversion K --> ºC).
