now be used to increase <strong>the</strong> reliability of information that is fed into models for monitoring and<br />

forecasting. The Australian Commonwealth Scientific and Research Organization (CSIRO)<br />

currently rely on optical data in combination with passive microwave technologies and digital<br />

elevation models. Incorporating ASAR in <strong>the</strong> system would result in several advantages: on one<br />

hand, reliability and accuracy increases <strong>through</strong> higher resolution, while, on <strong>the</strong> o<strong>the</strong>r, cloudindependent<br />

continuous monitoring is possible. Figure 3 illustrates relative soil moisture<br />

saturation on Australia’s Eastern coast during <strong>the</strong> flood events of December 2010.<br />

2.6.3 Satellite Application Facility on Support to Operational Hydrology and<br />

Water Management (H-SAF)<br />

H-SAF was established by <strong>the</strong> EUMETSAT Council in July 2005. The Development phase<br />

started in September 2005. Within <strong>the</strong> H-SAF framework <strong>the</strong> focus for new satellite products lies<br />
