Data Terra research infrastructure: from data to knowledge of the Earth system

Who we are ?

Data Terra “data and services clusters for the Earth system” is included in the national roadmap 2016, 2017 and 2021 of the IR/TGIR of the Ministry of Higher Education, Research and Innovation (MESRI).

The main mission of Data Terra is to develop a global system for accessing and processing data, products and services that will enable the integrated observation, understanding and prediction of the history, functioning and evolution of the Earth system under global change. Intended for the scientific community as well as for public and socio-economic actors, these multi-source data, products and services are accessible through a unified and coherent portal.

As a digital infrastructure for the environment domain, Data Terra acts in close collaboration with observational IRs and space agencies. It relies on distributed, interconnected platforms and offers services that facilitate the cross-referencing and exploitation of very large volumes of data and the generation of information combining products from multiple sources. In Europe and internationally, it contributes to FAIR (EOSC) approaches, space missions and applications, and the implementation of digital twins of the Earth.

One of Data Terra’s major ambitions is to federate and optimize existing institutions, structures and resources at national, European and international levels. Data Terra is built around four data hubs each focused on one of the key components of the Earth system: land surfaces, atmosphere, oceans and solid Earth, complemented by working groups and a cross-cutting service.on)

This IR is based on four data poles corresponding to each of the major compartments of the Earth System:

  • THEIA for continental surface data (agriculture, forests, biodiversity …)
  • AERIS for atmosphere data (gases, aerosols, clouds …)
  • ODATIS pour les données océan (altimétrie marine, phytoplancton, pigmentation …)
  • ForM@Ter for solid earth data (volcanoes, erosion, tectonics …

Each cluster aims to facilitate access to satellite, airborne and in-situ data. These data come from multiple sources: satellites, space missions, airplanes, sounding balloons, oceanographic fleets, etc. They can be acquired and managed by research laboratories, federative structures (OSU, FR, etc.), national infrastructures such as the National Observation Services (SNO), or long-term observation and experimentation systems for environmental research (SOERE).

Working groups and cross-cutting services such as the National Institutional Device for Mutualized Supply of Satellite Imagery (DINAMIS) are also integrated into the Data Terra IR.

Coordinating, federating and optimizing all existing institutions, facilities and resources is one of the important ambitions of IR Data Terra, at the national, European and international levels.

The goals of Data Terra

  • Promote access to multi-source data
  • Develop services for the entire data cycle
  • Develop quality products and services that meet the FAIR criteria for all the compartments of the Earth system and their interactions
  • To coordinate, federate and optimize within a single research infrastructure all the existing institutions, devices and means in the field
  • To promote mutualization, interdisciplinarity and interoperability
  • Implement integrated approaches for the use of Earth observation data
  • Participate in international and European initiatives in support of public policies for sustainable development

Activity report 2017 – 2020

The DATA TERRA research infrastructure publishes here the activities carried out since 2014, when the four data poles were created under the coordination of the main tutelles. The opportunity to review the progress of the implementation of the strategy of the institution: structuring, governance, scientific strategy, technical developments, development of European projects, links with observation IR, space strategy and activities of each of the poles.
