      CryoSat campaigns data to be studied in support for SWOT

      2016-12-08

      Cryosat "SARIn" mode, using its two antennas, is meant for surfaces with steep slopes - so not open ocean, in particular. However, ESA has been rolling the satellite on its side to calibrate the instrument, generating an "artificial slope" with respect to the ocean surface. This generates "swath-like" data and thus can approach what we will have with SWOT. The data acquired during the seven roll campaigns are now released publicly released to all users.
