  • 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
    The first altimetry mission was Geos-3, from 1975 to 1978, which had an accuracy of 100 cm Seasat, which only operated for about three months in 1978, was twice as accurate (50 cm) The highly successful Navy Geosat mission, 1985–1989, was also accurate to 50 cm and operated for four years, providing the first high-quality altimetric dataset The Geosat mission was the first to employ an
  • 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 river water level retrieval over complex environments . . .
    Satellite altimetry has been increasingly used in monitoring inland water bodies Waveform retracking plays a major role in water level retrieval How…
  • A global intercomparison of SWOT and traditional nadir radar altimetry . . .
    Satellite nadir radar altimetry is an Earth Observation technique which allows the retrieving of the surface height (h) by computing the difference between the altitude of the satellite (H)—determined with a centimeter-level accuracy using precise orbit determination techniques—and the distance between the satellite and the surface (R 0)
  • Satellite Altimetry - an overview | ScienceDirect Topics
    Satellite altimetry is defined as a technique for measuring heights of the Earth's surface from a satellite, primarily focused on sea surface height, with an accuracy of about ±1 cm on a global scale It involves measuring distances from the satellite to various surfaces such as oceans, lakes, rivers, and ice, enabling the creation of surface profiles along satellite orbits AI generated
  • A review of altimetry waveform retracking for inland water levels
    In recent decades, satellite altimetry has become a valuable supplement for inland water applications This technology has enabled remote and regular observation of water levels over lakes, rivers, and reservoirs [[5], [6], [7]] Among the inland water bodies, smaller ones have an important role in the water cycle [8, 9] New altimetry missions (e g , ICESat-2, Sentinel-6, SWOT) offer

    GPS L1 C A intermediate-frequency signal processing of the CYGNSS and accuracy optimization for sea surface altimetry
  • A review of the evolution of satellite radar altimetry for hydrological . . .
    Satellite altimetry has become essential for accurate and reliable assessment of river levels using remote sensing It complements in-situ measurements and overcomes their limitations The ongoing development of this field emphasizes its importance in the study of hydrology and the management of water resources
  • Mountain snow depth retrievals from customized processing of ICESat-2 . . .
    The water resources community needs accurate snow depth data for improved basin-wide snow depth estimates The NASA ICESat-2 mission has provided over four years of global satellite laser altimetry measurements since October 2018
