 v16 ==  Function: == A python function has been created in order to access the ''SPECS-EUPORIAS Data Portal'' in a user-friendly way, allowing the retrieval of dimensional slices of selected simulation members from the ECMWF's SYSTEM4 model. This function ([browser:software/specseuporias/dataserver/python/load_system4.py load_system4.py]) automatically cares about the proper location of the right indices for data sub-setting across the different variable dimensions, given a few simple arguments for subset definition. In addition, instead of retrieving a NetCDF file that needs to be opened and read, the requested data is directly loaded into the current python working session, according to a particular structure described below, prior to data analysis and/or representation.

The request is simply formulated via the loadSystem4 function:
