Spacecraft autonomy is becoming an important aspect of the design and operation of future space missions. While science objectives continually increase, budgets for development and operations remain fairly flat. Implementing spacecraft autonomy may help in achieving these goals, while reducing operations costs. Autonomy algorithms have been developed and tested using ground simulations, however...

AbstructA recently developed multiresolution estimation framework offers the possibility of highly efficient statistical analysis, interpolation, and smoothing of extremely large data sets in a multiscale fashion. This framework enjoys a number of advantages not shared by other statistically-based methods. In particular, the algorithms resulting from this framework have complexity that scales o...

Two years of TOPEX/POSEIDON altimeter data have successfully been used to study the mesoscale field in the Mediterranean and to investigate the seasonal and year-toyear variability of the sea level and eddy statistics in this basin. The mesoscale field described by TOPEX/POSEIDON revealed a strong, but subbasin dependent, seasonal signal. Year-toyear variations are also evident in terms of both...

[1] We develop a spectral inversion method for mass redistribution on the Earth’s surface given geodetic measurements of the solid Earth’s geometrical shape, using the elastic load Love numbers. First, spectral coefficients are geodetically estimated to some degree. Spatial inversion then finds the continental surface mass distribution that would force geographic variations in relative sea leve...

A dynamically consistent steady state circulation pattern of the North Pacific (NP) ocean is presented. The fields describing oceanic state and atmospheric forcing are obtained by fitting a steady state large-scale circulation model to the 1.0 release of World Ocean Circulation Experiment hydrology, da Silva atmospheric climatologies, TOPEXPoseidon altimetry, and Marine Environmental Data Servi...
