Summary<br />
Satellite products can be evaluated directly aga<strong>in</strong>st model<br />
products (<strong>in</strong>cl. Triple Colocation).<br />
Satellite products can be evaluated with<strong>in</strong> data assimilation<br />
systems (<strong>in</strong>cl. Monitor<strong>in</strong>g <strong>and</strong> R-value approach).<br />
<strong>Model</strong> products <strong>and</strong> data assimilation methods enable:<br />
• near-global evaluation,<br />
• cont<strong>in</strong>uous <strong>and</strong> near-real time assessment,<br />
• evaluation at the appropriate scale, <strong>and</strong><br />
• use of additional observations (e.g. precipitation, vegetation).<br />
<strong>Model</strong> products <strong>and</strong> assimilation systems are not perfect. Their<br />
use <strong>in</strong> evaluation only supplements core-site validation!
