Abstract. Against the backdrop of global change, in terms both climate and demography, there is a pressing need for monitoring water cycle. The publicly available database very limited its spatial temporal coverage worldwide. Moreover, acquisition situ data their delivery to have been decline since late 1970s, be it economical or political reasons. Given insufficient from gauge networks, with n...

Radar altimetry is now commonly used for the monitoring of water levels in large river basins. In this study, an altimetry-based network of virtual stations was defined in the quasi ungauged Ogooué river basin, located in Gabon, Central Africa, using data from seven altimetry missions (Jason-2 and 3, ERS-2, ENVISAT, Cryosat-2, SARAL, Sentinel-3A) from 1995 to 2017. The performance of the five l...

High-precision orbits of Low Earth Orbit (LEO) satellites are essential for many scientific applications, such as assessing the change in current global mean sea level, estimating coefficients gravity field, and so on. How to determinate high-precision LEO has gradually become an important research focus. HY2D is a new altimetry satellite China, which equipped with Global Positioning System (GP...

 The factors that determine the success of the crop is water content in the soil profile explored by the roots, where soil and management condition affect the storage and availability. Because of the sites defined by the altimetry and crops predecessors affect the behavior of water content stored in the soil available for plants.  The aim of this work was to analyze the relationship between d...

New high-resolution Geosat altimetry data south of 30°S reveal numerous propagating ridge wakes along intermediateand slow-spreading ridges. These new examples provide a large enough database to establish systematics of ridge propagation. Almost all active propagating ridges propagate down a regional along-axis gravity or bathymetry gradient. The sense of the propagating ridge offset (right lat...

The Doctorate of Geomatics and Infrastructures continues the tradition of the previous Doctorate in Geodesy and Geomatics, dating back to the first cycle of doctorates in Italy of the years 1983-86. Thus, according to the vision of the Doctorate School of Politecnico di Milano, we are working now within an interdisciplinary environment. The original field of geomatics, which in any way was alre...

Only approximately 20% of the global seafloor topography has been finely modeled. The rest either lacks data or its are not accurate enough to meet practical requirements. On one hand, satellite altimeter advantages large-scale and real-time observation. Therefore, it is widely used measure bathymetry, core topography. However, there often room improve precision. Multibeam sonar bathymetry more...
