Estimation of the Geophysical Parameters Effect on the Altimetric Measurements for Sea Surface Height Determination | Chapter 08 | Theory and Applications of Physical Science Vol. 2
The emergence of satellite altimetry
has allowed us to determine the ocean surface with a great precision; it also
allows a large contribution for most applications and oceanographic activities.
The geometric principle of space altimetry is to measure the range between the
satellite and the sea surface.
The objective of this paper is to estimate the geophysical parameters (sea
state bias and ocean tide) affecting the altimetric measurements for Jason-1
satellite, using the analytical and empirical models.
The comparison of the estimated and provided values permit to minimize the
default values for SSB and improve its estimation, and also improve the ocean
tide estimation.
The comparison of obtained results of
six (6) years Jason-1 data processing on the western Mediterranean of every
parameter with data transmitted in the satellite message permitted us to
validate our developed methodological approach. The quality of these results
permits the determination of the Western Mediterranean mean sea level.
