Modifications to the Data System backends

The last days the backends for the SIOS Data Management System have been upgraded and a number of new datasets and functionality have been added

It is now possible to visualise and transform (NetCDF/CF to comma separated files) time series if they are served in the appropriate form from the host data centre. In addition information from WMO GTS (real time exchange of meteorological information) in the Arctic is added to the catalogue.
