Using the latest corrections available in the CTOH database, CTOH computes a coastally-adapted Sea Surface Height (SSH) along the satellites ground-track for each cycle. Additionnal geophysical corrections are applied accounting for the aliasing of tides and short-term atmopheric effects in the SSH measurements. Details on selected corrections are given here. The Mean Sea Surface (MSSH) is computed at each point, based on the mission period currently available, and subtracted from the corrected SSH in order to form the SLA. The SLA are finally projected onto a reference track with a spatial interval of about 7 km between points (1 second). For every region, both the raw SLA and a 40-km along-track filtered SLA produc are distributed.
