<Attribute name="summary" type="String"><br />
<value>Surface ocean velocities estimated from HF-Radar are&#x0a;representitive of the upper 0.3 - 2.5 meters of the&#x0a;ocean. The main objective of near-real time&#x0a;processing is to produce the best product from&#x0a;available data at the time of processing. Radial&#x0a;velocity measurements are obtained from individual&#x0a;radar sites through the HF-Radar Network and&#x0a;processed to create near-real time velocities&#x0a;(RTVs)</value><br />
