Personal information
Scientific information
sea-ice-products   Select wanted sea ice product(s). All the products include the freeboard (FB), the snow depth (SD) and the sea ice thickness (SIT). The last ones also provide the SLA but for a shorter period. The South Hemisphere SLA is still under processing.

The CTOH (Centre de Topographie des Océans et de l'Hydrosphère) is a French National Observation Service, supported by INSU (Institut National des Sciences de l'Univers). Its role is to assist scientific users and the different space agencies in the development of new altimetric applications. To this end, the CTOH provides access to their frequently updated altimetric data bases, including Topex-Poseidon, Jason-1, Jason-2, GFO, and ENVISAT data, and to the altimetric products developed by the CTOH.

CTOH products are provided free of charge under the condition that they are exclusively used for scientific studies and experiments. This implies that:
    - Copying the CTOH Products for use by third parties is strictly forbidden.
    - Granting access to the CTOH Products for use by third parties is strictly forbidden.
    - Commercial use of the CTOH products, or products directly derived from them, is strictly forbidden.

We ask that the users keep us informed of their publications using the CTOH data products.
We also ask that the users communicate us any problems they find with the data products.

Finally, as standing in a research approach including the measurements themselves, the CTOH cannot be held for responsible for the scientific utilisations of the data.
