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 (? 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 load_system4 function:

>>> load_system4(dataset, var, season, leadMonth, lonLim, latLim, year, members=[])

The arguments of the function are described below:

Short NameLong nameUnitsInstantaneousAggregated
tasmax Maximum temperature at 2 metres degCNoYes
tasmin Minimum temperature at 2 metres degCNoYes
tas Mean temperature at 2 metres degCYesYes
pr Total precipitation accumulatedmmNoYes
mslp Mean sea level pressure PaYesYes

The output returned by the function consists of a list with the following elements providing the necessary information for data representation and analysis:
