LICENCE TO USE AVISO+ PRODUCTS

Issue 8 - April 2015

IMPORTANT NOTICE: PLEASE READ CAREFULLY BEFORE USING AVISO+ PRODUCTS

This Licence Agreement is a legal agreement between the Licensee, the CNES and CTOH and sets out the terms for use of AVISO+ Products which will apply to the Licensee. Use of AVISO+ Products means that the Licensee agrees to abide by all of the terms and conditions in this Licence..

Introduction

  • i. CNES operates a multi-satellite altimetric ground segment called SSALTO (Segment Sol ALTimétrie et Orbitographie) which provides level 2 geophysical altimetry products. SSALTO provides also level 3 along track products and level 4 gridded products via SSALTO/DUACS system, as well as auxiliary products used in the frame of the processing of the Level 2 products.
  • ii. All the products elaborated by SSALTO and SSALTO/DUACS are available to Users via the AVISO+ system in charge of products access and dissemination.
  • iii. 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), the CNRS (Centre National de la Recherche Scientifique), the CNES (Centre National d'Etudes Spatiales), UPS (Université Paul Sabatier) and IRD (Institut de Recherche pour le Développement). Its role is to assist scientific users and the different space agencies in the development of new altimetric applications.
  • iv. In the frame of the Copernicus Marine Environment Monitoring Service (CMEMS) development, several historical SSALTO/DUACS products are now disseminated by CMEMS as primary provider. Nevertheless, in order to help SSALTO/DUACS users during the migration period, AVISO+ is authorized, by signing the CMEMS “Service commitments and licence”, to redistribute CMEMS products to third parties.
  • v.AVISO+ Products are listed in the AVISO+ Catalogue.

1. Interpretation and Definitions

AVISO+ Catalogue means the list of AVISO+ Products made available via the AVISO+ website to the Licensee at any given time;

AVISO+ Product(s) means those products created by SSALTO or SSALTO/DUACS or CTOH and made available for use via the AVISO+ catalogue; different types of products exist:

  • Level 2: validated geophysical altimetry products. They are available in different formats depending of the satellite mission
  • Level 3: along-track altimetry products as SLA (fully corrected Sea Level Anomalies) and ADT (Absolute Dynamic Topography). They result from an optimal cross calibration of all in-flight altimetry satellites and are available in near real time and offline.
  • Level 4: gridded products resulting from optimal analysis as mapped SLA and mapped ADT.
  • Auxiliary products: products developed for Level 2 processing, and used as correction of altimetry heights (heights from FES tide model, Dynamic Atmospheric Correction DAC) or as reference surfaces (Mean Dynamic Topography MDT, Mean Sea Surface MSS). Indicators, in-situ data.
  • CTOH demonstration products: These are non-operational altimetry products computed with new algorithms and techniques. By definition, the CTOH products list will evolve over time. Currently, CTOH products include:
    • Along track coastal altimetry products, based on the CTOH/-X-TRACK data processing.

7. Availability commitment

The level of operationality of AVISO+ products depends on the type of product and the mission.

The core products of altimetric missions (typically level 2 geophysical data processed by CNES) are processed by operational ground segments, delivery delays mentioned on the AVISO+ website are defined as mission requirements and all human and material means are used to meet those requirements and avoid delivery delays.

Concerning AVISO+ level 3 and level 4 products processed by the multimission SSALTO/DUACS system, they are processed on operational systems and their delivery is considered as operational.

AVISO+ Auxiliary products, indicators and in-situ products are updated regularly on a reasonable-effort basis (except MSL considered as operational indicator).

For expertise and demonstration products such as PISTACH, PEACHI, X-TRACK, no operational commitment are defined. Mean delivery delays are indicated on the AVISO+ website but they are not a formal commitment from CNES and CTOH as the product processing is made on a reasonable-effort basis.

See the appendix table summarizing operational commitments for more details.

8. Intellectual Property Rights

8.1. All Intellectual Property Rights in AVISO+ Products belong, and will continue to belong, to CNES or CTOH.

This property is protected by the copyright under French Law and according to the terms of international conventions applicable. It is also protected by articles L 341-1 to 343-4 of the Industrial Property Code as modified by the French law dated July 1st, 1998, relating to the protection of databases and similar laws in European countries, which have transferred European directive No. 96/9, dated March 11, 1996, on the protection of databases, to their respective legislations.

8.2 All new Intellectual Property Rights created as a result of modifying or adapting AVISO+ Products will be owned by the Licensee.

9. Disclaimers

9.1 CNES AND CTOH DO NOT WARRANT THAT AVISO+ PRODUCTS WILL BE FREE FROM ERRORS OR OMISSIONS AND THAT SUCH ERRORS OR OMISSIONS CAN BE RECTIFIED, OR THAT THE LICENSEE WILL HAVE UNINTERRUPTED ACCESS TO AVISO+ PRODUCTS.

9.2 CNES AND CTOH EXCLUDE ALL OTHER WARRANTIES, CONDITIONS, TERMS, UNDERTAKINGS, and OBLIGATIONS WHETHER EXPRESS OR IMPLIED BY STATUTE INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF SATISFACTORY QUALITY AND FITNESS FOR A PARTICULAR PURPOSE OR OTHERWISE TO THE FULLEST EXTENT PERMITTED BY LAW.
