Mars and Mercury rotation variations from altimetry crossover data: Feasibility study

Global Surface Mass Variations from Continuous GPS Observations and Satellite Altimetry Data

The Gravity Recovery and Climate Experiment (GRACE) mission is able to observe the global large-scale mass and water cycle for the first time with unprecedented spatial and temporal resolution. However, no other time-varying gravity fields validate GRACE. Furthermore, the C20 of GRACE is poor, and no GRACE data are available before 2002 and there will likely be a gap between the GRACE and GRACE...

Energy characteristics of tidal and residual level variations in the Okhotsk Sea from satellite altimetry data

A unified satellite altimetry database, TOPEX/Poseidon (1993–2002) and Jason-1 (2002–2007) containing about 7,000 locations, was created for the Okhotsk Sea and adjacent areas. Amplitudes and phases of main tidal consituents were calculated for each location, and maps of tidal character and height were constructed. It is shown that diurnal waves dominate in the amphidromic areas of semidiurnal ...

Radar Altimetry of Mercury' A Preliminary Analysis

Measurements of Mercurian topography based on Arecibo radar observations are presented. The data, which were obtained from 1978 to 1984, cover much of the equatorial zone of Mercury between 12øN and 5øS latitude. Over thirty continuous altitude profiles were obtained, each spanning from 20 to 90 degrees of longitude at a resolution of 0.15 ø (longitude) by 2.5 ø (latitude). Radar depths for lar...

Combined Bundle Adjustment of Moc Stereo Images and Mola Altimetry Data for Precise Mars Topographic Mapping

Launched in 1996, Mars Global Surveyor (MGS) carries two types of mapping equipments: Mars Orbiter Laser Altimeter (MOLA) and Mar Orbiter Camera (MOC). MOLA collects accurate laser altimetry data over the Mars surface, while MOC acquires high resolution images. In the process of MOLA registration to MOC images, a certain systematic shift was reported in previous studies. This shift may possibly...
