The Radar Altimeter Database System (RADS) is an initiative funded by the Dutch government to establish a harmonised, validated and cross-calibrated sea level database of satellite Altimeter data.

Calibration and validation of the raw data, secondary data and the measurements themselves have been performed as well as the harmonisaton of any geophysical corrections. All data is publicly available and covers the following Altimeters:

  • ERS-1
  • TOPEX/Poseidon
  • ERS-2
  • GFO-1
  • Jason-1
  • Envisat
  • Jason-2

A single format and quality flag approach has been defined to cover these instruments.
