Observation networks and NRT data transmission: case studies and integration

Near Real Time (NRT) monitoring systems, at sea and in coastal areas, are be- coming more and more important in many fields. Especially when they are coor- dinated within networks of inter-operated data sources, they can become the key for models validation, early warning and decision support systems and setting. Furthermore these actions are able to provide informations for long-term time series of metorological and oceanographical data. The building blocks of these networks can be summarized into three main levels: instrumental (deployment and maintenance), data transmission and control, validation and data delivery. All of them require efforts for medium and long term management and for data format standardization. CNR Institutes have established several meteorological and oceanographical ob- servation points at sea for: fixed platforms, moored buoys and ocean-going research ships. We present some implementations of NRT data transmission (tipically few minutes from the acquisition) from this network, aiming toward a better integration into National and worldwide Observation Systems.
