Satellite topex/poseidon
Description
The data were registered by the satellite topex/poseidon around an area of 25 kilometers upon the Amazon River. Each row of the data matrix is represented by its wave (i.e. curve) on the range (0, 70), and the satellite is registering 10 curves each second.
Usage
data(Satellite)
Format
An object of class fds.
Details
Note that each wave is linked with the kind of ground treated by the satellite, and the idea for the Amazonian basin is to use these waveforms for altimetric and hydrological purposes.
Note
We thank Professor Frederic Ferraty for the permission to re-distribute this data set.
