We have processed radar altimeter data from more than 100 Geos 3 passes. The statistical analysis of the stretching of the leading edge of the return radar pulses gives us an estimate of the significant wave heights, as reported by other scientists. Moreover, the automatic gain control level measurements of the reflected power provide an evaluation of the wind speed. The wave height and wind speed estimates are in favorable agreement with the meteorological information obtained from weather maps used as sea truth, thus resulting in interesting complementarities
