CONTENTS

This is a global product giving values at regular intervals along the satellite track of surface range, satellite altitude, windspeed and significant wave height at nadir, and the altimeter waveform data. It is processed using the precise orbit and giving full geophysical corrections. The WAP product includes both data over ocean, ice and land. Since 22 June 2003 dataset are limited to ground station visibility.
