Abstract:
The Center for Topography of the Oceans and Hydrosphere (CTOH) is a French Observation Service created in 1989 and dedicated to the dissemination of satellite altimetry products and knowledge. It focuses on the development and improvement of new processing approaches of the altimetric data for emerging research domains (coastal ocean, oceanic sub-mesoscale phenomena, continental surface water). It works in close relationship with space agencies (mainly CNES and ESA) at different levels for satellite altimetry missions: preparation of new missions, definition of the user’s needs, CAL/VAL studies, signal analysis & data reprocessing, development of thematic products, teaching and outreach.
In terms of data distribution, the CTOH maintains a global GDR data base for almost all altimetry missions since Topex/Poseidon. All the products are made homogeneous by providing up to date altimetry corrections to historical missions, and providing all products in NetCDF format.
For the hydrology community, this poster presents the latest developments of the AlTiS software package, which enables the construction of time series of altimetry products if a continental surface water context. We also present the development of the new virtual station product based on CTOH's SINC retracker.
For the coastal community we present the latest version of the X-TRACK L2P product, based on the latest altimetry standards for the Topex/Jason-1/Jason-2/Jason-3, ERS/Envisat, Sentinel, Geosat and HaiYang-2A missions. The FDR4ALT coastal product is presented as well.
For open-ocean applications, an updated multi-satellite Southern Ocean fronts product is presented.
