These L4 products are meant for statistics and visualization.The altimeter data used in the Sea State CCI dataset v4 come from multiple satellite missions spanning from 1992 to 2023 ( ERS-1, ERS-2, Topex-Poseidon, Envisat, CryoSat-2, Jason-1, Jason-2, Jason-3, SARAL, Sentinel-3 A, Sentinel-3 B, Sentinel-6 A), therefore spanning over a larger time range than the previous version 3 (2002-2021). Many altimeters are bi-frequency (Ku-C or Ku-S) and only measurements in the Ku band were used, for consistency reasons, being available on each altimeter but SARAL (Ka band)." ;
