About this Research Topic
Many satellite altimetry missions have been implemented since 1975 and one new swath altimetry technique has been gradually developed. The large amount of radar and laser altimeter data collected from multi-satellite missions are precisely processed and widely used to study marine geodesy and geophysics. Sea level rising and ocean mass change are threatening the marine environment under effects of global climate change, which have also been studied using altimeter data. The sea surface height accuracy determined from radar altimeter data can be up to a level of 2-4 cm over open oceans, but it drops to a level of 10 cm over coastal seas. With the development of satellite altimeter technology, there have been many achievements in marine geodesy and geophysics by combining multi satellite altimeter data. Also satellite altimetry has wide applications over inland waters (rivers, lakes).
This Research Topic aims to gather contributions on satellite altimeter data processing and applications in marine geodesy and geophysics, as well as applications over inland waters. Radar altimeters of C-band, Ka-band and Ku-band have collected waveforms over oceans which are contaminated by compressed pulse, atmosphere, sea state, geophysical environment and reflective surface. Laser altimeters can simultaneously receive interesting signals but also noises. Therefore, the satellite altimeter data quality should be further improved. Satellite missions (e.g., exact repeat orbit, drifting orbit and geodetic missions) execute to collect sea surface heights over open oceans and coastal seas. Unified time and space datum and altimeter data fusion are very important to study marine geodesy and geophysics. Quality estimations of sea surface height, marine gravity field and vertical deflection, sea depth and ocean current will support studies in oceanography, marine geodesy and geophysics.
We welcome articles addressing, but not limited to, altimeter data quality improvement, altimeter data processing method, multi-source data fusion, new altimetry technique, mean sea surface height model, dynamic ocean topography, marine gravity anomaly, marine deflection of the vertical, marine gravity gradient, marine bathymetry, sea level change, ocean mass change, sea ice detection, ocean tide model, ocean dynamics, coastal deformation, seafloor geological structure and evolution, marine earthquakes, tsunamis and inland water level monitoring of rivers and lakes. Original Research, Method and Review articles on the interdisciplinary studies of geodesy, geophysics and oceanography based on satellite altimetry technology are particularly welcome.
Accordingly, we welcome submissions in the following major themes but not limited:
• Radar/laser altimeter data processing methods and algorithms;
• Marine gravity field modelling and its applications;
• Sea surface variation modelling and ocean mass change;
• Ocean, seabed and coastal dynamics; and
• Inland water level monitoring.
