Support of non gridded datasets extraction and donwloading services, such as along-track L2-L3 products. Use of an OGC Observations&Measurements based data model (CSML..) Support of 'exotic' products such as ocean indicators (mean sea level..) In situ data (ARGOS..): OGC Sensor Observation Service? In fine propose an integrated solution to manage the heterogeneous datasets we are dealing with.. The future and hopes..
