- Altimetry for the future: Building on 25 years of progress
In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oc…
- Altimetry - an overview | ScienceDirect Topics
Altimetry for polar ice caps started in 1991 with the launch of the European satellite ERS-1 In almost 25 years, this instrument has allowed us to make progress on numerous subjects However, relatively cumbersome processes of different complexity were necessary, from reprocessing of the waveform to the construction of a topographic map
- Altimetry - an overview | ScienceDirect Topics
Satellite altimetry is a technique of measuring heights of the Earth's surface from a satellite flying at an attitude of about 1000 km The objective of altimetry is to measure principally sea surface height to an accuracy of about ±1 cm, continuously, objectively, and on a global scale
- A review of altimetry waveform retracking for inland water levels
Altimetry missions, including radar and laser altimetry, have provided data that greatly enhances the accuracy of nadir-ranging-based water levels The majority of altimetry data are from nadir radar altimeters Radar altimetry data processing has improved tracking, geophysical correction, and waveform retracking
- Fiducial reference systems for time and coordinates in satellite altimetry
New altimetry missions, such as Sentinel-6 Jason-CS, CRISTAL (Polar Ice and Snow Topography) but also other international or national altimeters such as SWOT (Morrow et al , 2019), HY-2C, Quanlan (Chen et al , 2019), among others, and the operational Sentinel-3, Jason-3, HY-2B, CryoSat-2, IceSat-2, set new standards and expectations for time
- Advances in estimating Sea Level Rise: A review of tide gauge . . .
The quasi-global satellite altimetry confirmed that the variations in sea level is ocean-wide, providing further insights on tide gauge measurements which suggest regional variability Complementing tide gauge data with satellite altimetry data would increase existing knowledge of global, regional and coastal sea level variations
- Tides modeling using satellite altimetry across Southeast Asian seas
Satellite altimetry missions that started in 1993 have compassed unprecedented accuracy in absolute sea-level measurement for ocean tide analysis Contemporarily, the availability of the repeated sea surface height (SSH) from satellite altimetry for almost three decades has enabled the majority of tidal constituents to be extracted separately
- Reconstructing Tibetan Plateau lake bathymetry using ICESat-2 photon . . .
Altimetry crossovers (Shum et al , 1990) are defined as the orbital crossing points in space at two different times from satellite's ascending and descending tracks For a designed exact-repeat orbit for satellite altimetry, the crossover locations largely remain stationary over the Earth, providing an excellent dataset for assessing height
