The Jason-1 (GDR-C) and Jason-2 (GDR-T) data were
provided by AVISO. They respectively cover the periods
from cycle 1 to cycle 332 (January 2002 to January 2011)
and from cycle 1 to cycle 93 (July 2008 to January 2011).
The Jason-1 mission was shifted on the interleaved orbit
in January 2008. Consequently, part of the cycles (1 to
259 – January 2002 to January 2009) is available on the
nominal orbit, whereas the rest is located on the interleaved
orbit (263-332 – February 2009 to January 2011).
