Abstract. A total of 13 satellite missions have been launched since 1985, with different types radar altimeters on board. This study intends to make a comprehensive evaluation historic and currently operational altimetry for lake water level retrieval over the same set lakes develop strategy constructing consistent long-term records inland at global scale. The estimates produced by retracking a...

In the context of ESA Climate Change Initiative project, a new coastal sea level altimetry product has been developed in order to support advances variability studies. Measurements from Jason-1,2&3 missions have retracked with Adaptive Leading Edge Subwaveform (ALES) Retracker and then ingested X-TRACK software best possible set corrections. These two processing approaches, previously successfu...

Almost one year of TOPEX/Poseidon (T/P) and Jason-1 data are processed to analyze the contribution of the tandem mission to mesoscale studies. To merge T/P and Jason-1 sea level anomaly (SLA) data, the main difficulty is to estimate consistent mean profiles for the two missions. An ocean variability correction is thus applied to T/P data before computing the mean profile. As a result, T/P and J...

AgentSpeak and its practical interpreter Jason represent an excellent framework for implementing complex, reasoning agents. This paper discusses an ongoing research dedicated to extending Jason with the support for soccer playing agents. The end goal is to design an efficient infrastructure, capable of deploying and running BDI agents in the RoboCup soccer simulation league. 1 Intelligent agent...

The resolutions of current global altimetric gravity models and mean sea surface are around 12 km wavelength resolving 6 features, for many years it has been difficult to improve the resolution further in a systematic way. For both Jason 1 2, Geodetic Mission (GM) carried out as part Extension-of-Life phase. GM Jason-1 lasted 406 days. Jason-2 was planned provide ground-tracks with spacing 4 af...

Using a 25-y time series of precision satellite altimeter data from TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3, we estimate the climate-change-driven acceleration of global mean sea level over the last 25 y to be 0.084 ± 0.025 mm/y2 Coupled with the average climate-change-driven rate of sea level rise over these same 25 y of 2.9 mm/y, simple extrapolation of the quadratic implies global mean...

Near-real time altimetry products from ENVISAT RA2, Jason 1 and Topex/Poseidon tandem mission are validated for the North Sea and Baltic Sea region to assess the feasibility of using the data for operational purposes. The coverage of the satellite data shows that all Jason 1 and Topex/Poseidon observations in the Baltic Sea are currently discarded in the processing of the data. The spatial scal...
