[3] Although previous attempts have had some success detecting relatively weak tsunamis in satellite altimeter data [cf. Okal et al., 1999], the Sumatra event was the first major tsunami detected by satellite altimetry. Moreover, the event was observed by four satellite systems (TOPEX/POSEIDON, Jason, Envisat and Geosat) rather than just a single system. The Jason-satellite, operated jointly by NASA and the French space agency (CNES), was strategically placed during cycle 109, track 129 [Gower, 5], providing accurate measurement of the tsunami wave height in the Indian Ocean. Here, we use sea surface altimetry data provided by the Jason-1 track to examine the dispersive characteristics of the open ocean tsunami waves as they propagated from the source area westward toward India and Sri Lanka.
