The CTOH is a French Observation Service dedicated to satellite altimetry studies (Centre of Topography of the Oceans and the Hydrosphere) . The CTOH aims to help scientific users develop new altimetric products and applications.
Within this framework, the CTOH maintains homogeneous altimetric data bases for the long-term monitoring of sea level and ocean currents, lake and river levels, the cryosphère, and the planet's climate.
Scientific users can extract :
alongtrack GDR data with up-to-date corrections, over oceans and continental surfaces, for different altimetric missions (Topex/Poseidon, Jason-1, Jason-2, GFO, ENVISAT).
alongtrack GDR data with specific X-TRACK processing
surface currents (Geostrophic and Ekman) from 1999-2008
- submesoscale filaments (FSLE) available globally for the period 12/2000-04/2009
Established in 1989, the CTOH is an INSU Observational Service, supported by the Centre National de la Recherche Scientifique (CNRS), Centre National d'Etudes Spatiales (CNES), Observatoire Midi-Pyrénées (OMP), Pôle Océan-Altimétrie-Climat (CPER).
