Our mission
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. The CTOH team collaborates with different scientific investigators
to improve the quality of the altimetric measurements and their derived
products, and to facilitate their use by scientists. The CTOH is also an independent centre of expertise for the primary
data distribution centres (AVISO for Topex/Poseidon, Jason-1 and
ENVISAT in Toulouse; ESA at ESRIN, Italy, and CERSAT for ERS1/2 in
Brest), and for preparing future altimetric missions. Today, new scientific applications for altimetry are appearing :
monitoring lake and river levels, the study of the continental snow and
the cryosphere, flooded zones, coastal applications. The CTOH
contributes to the processing and management of the altimetric data for
these "emerging" research domains. Established in 1989, the CTOH is an INSU 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).
