Remote Sensing plays a critical role in operational volcano monitoring due to the often remote locations of volcanic systems and the
large spatial extent of potential eruption pre-cursor signals. Despite the all-weather capabilities of radar remote sensing and despite
its high performance in monitoring change, the contribution of radar data to operational monitoring activities has been limited in the
past. This is largely due to (1) the high data costs associated with radar data, (2) the slow data processing and delivery procedures,
and (3) the limited temporal sampling provided by spaceborne radars. With this paper, we present new data processing and data
integration techniques that mitigate some of the above mentioned limitations and allow for a meaningful integration of radar remote
sensing data into operational volcano monitoring systems. The data integration concept presented here combines advanced data
processing techniques with fast data access procedures in order to provide high quality radar-based volcano hazard information at
improved temporal sampling rates. First performance analyses show that the integration of SAR can significantly improve the ability
of operational systems to detect eruptive precursors. Therefore, the developed technology is expected to improve operational hazard
detection, alerting, and management capabilities.
