Minimize How to access CryoSat data

The access and use of CryoSat products are regulated by ESA's Data Policy.

Registered users have free and open access to all CryoSat systematic data (Free Dataset) acquired according to the current geographical mode mask. The following ice and ocean data products are accessible on the CryoSat dissemination server

Products generated by the Ice Processor

  • FBR: SAR and SARIN
  • Level 1b: FDM, LRM, SAR and SARIN
  • Level 2 In-Depth (L2i): LRM, SAR, SARIN
  • Level 2: FDM, LRM, SAR and SARIN
  • GDR: Level 2 (LRM+SAR+SARIN) consolidated products over an orbit from ANX to ANX

Products generated by the Ocean Processor

  • Level 1b: IOP and GOP
  • Level 2: IOP and GOP

More information about products can be found in Cryosat Products Overview.

Online registration is available on the EOPI pages. The procedure foresees that after the submission of the registration form and acceptance of the Terms & Conditions, ESA will provide a specific CryoSat username and password within two working days. These credentials are different from the one selected by the user at the time of registration. Users can also register by sending an email to the ESA Earth Observation Helpdesk.

Registered users may access data directly via an ftp client at

Should users wish to receive large amounts of data (e.g. one year of global Level 1b SAR data) or intend to propose changes to the current geographical mode mask) a full proposal needs to be submitted as Cat-1 project.

Once the proposal has been reviewed and approved by the Mission Manager, Tommaso Parrinello, ESA will notify the user about the outcome of the review and, if positive, how to access data.

Any requests, questions, feedback or problems relating to CryoSat products should be addressed and sent to ESA Earth Observation Helpdesk.

DORIS CryoSat data is available from the IDS Data Centers. The IDS ftp sites are provided here for information only. Any problems related to the access of DORIS data should be address directly to IDS.
