ATLASOperationalProvide date on ice sheet height and sea ice thickness, land altitude, aerosol height distributions, cloud height and boundary layer height.n/a
IRISBeing developedKu-band Interferometric Synthetic Aperture Radar Altimeter (with added Ka-band channel for snow depth retrieval and in combination with AMR-CR MW Radiometer for ice&snow classification and wet troposphere correction) to cover the needs for continuous monitoring of sea ice thickness and land ice elevation measurement after Cryosat-2, with enhanced performance.n/a
LTIApprovedThe aim of MAGIC is to obtain high-resolution measurements in space and time and include the capability to determine the variations in gravity field due to mass change in hydrology, cryosphere, oceanography, solid Earth and climate change signals so as to serve science and operational products including emergency services.n/a
