Call for projects and AERIS data repository

The national centre for atmospheric data and services (AERIS) is responsible for the coordinated management of and centralised access to data from the ‘Atmosphere’ compartment of the Earth system. Its mission is to bring together all the observational and campaign data produced by the French atmospheric science community and to provide scientific users (the French and international scientific community) with a range of data, products and services enabling optimum use of the observation systems in this field for studies on local to climatic scales (AERIS services may be opened up to users outside the national or international scientific community). Research is based not only on ground, space and airborne observation data, but also on experimentation and modelling.
Depending on the nature of your data and your objectives, AERIS and Data Terra offer you several ways of depositing, publishing, saving, making accessible and visible your data:

  • If you wish to make a request for a service associated with data, you should respond to the AERIS permanent call for projects or contact the office, which will provide you with rapid guidance ( The AERIS permanent call for projects is open continuously. You can submit your project at any time using the following form:

However, for your project to be considered by the next AERIS Scientific Council, it must be submitted before the date indicated at the end of this page (SC meeting every 3 months). If the deadlines inherent in your project do not allow you to wait, do not hesitate to contact us directly (

  • If your project involves hosting research data of finite duration (projects or publications) whose acquisition/development, preservation and dissemination are not organised on a long-term or community basis (so-called long-tail data), you can use the Data Terra Repository.

Both the AERIS catalogue and the EasyData warehouse are connected to

Response to the call for projects

Objectives of the call for projects

The objective of AERIS is to support research requiring access to atmospheric data. To meet this need, AERIS provides the community with shared human and material resources by offering a call for projects that is open on an ongoing basis.
These projects may include:

  • Referencing or repatriating external data within AERIS to supplement existing data or enable new synergies;
  • Assisting in the use and analysis of data (extraction, production of composite assemblies, etc.);
  • The development of extraction, visualisation and analysis tools;
  • The systematic implementation of processing methods developed in the laboratories;
  • Demand for new products or services (e.g. useful products for model assimilation or validation, data distribution services, etc.);
  • Integration of an existing database within AERIS;
  • Hosting and structuring a campaign or major project database within AERIS;
  • Operational support for campaigns.
    The resources allocated may be material, based on AERIS archiving and calculation resources, or a combination of human and material resources. Selected applications will be awarded the AERIS label. Financial resources may be requested from applicants depending on the request (large storage space, significant human resources, etc.).


To ensure a flexible and responsive procedure, the application can be relatively short. It must, however, contain the information required by the AERIS Scientific Advisory Board to assess the scientific interest of the project (justification and motivation of the project) and technical information to enable us to estimate the working time and material resources required to carry it out.
This application will be assessed by AERIS in 4 stages over a period of approximately 3 months:

  1. Review of the projects submitted by the AERIS office: the office appoints the CDS (Data Centres and Services) in charge of the technical appraisal and a scientific rapporteur.
  2. Technical and scientific instructions: the CDS(s) and the scientific rapporteur contact the project leader in order to clarify the request (technical and scientific aspects) and to assess the workload.
  3. Assessment of the project by the AERIS Scientific Advisory Board
  4. Decision by the AERIS office and sending of the response: the decision is taken on the basis of the recommendations of the Scientific Council and the resources available.

For large projects, which can generally be anticipated, it is recommended that the AERIS office ( be informed as soon as possible and even before the project is submitted to the funding bodies, so that the AERIS management can be informed to help with the multi-year planning and, ultimately, the implementation of the project, and if necessary to provide for AERIS funding for the project.

EasyData Long-Tail Data Hosting

Long-tail data comes from research of finite duration (projects or publications), the acquisition/development, preservation and dissemination of which are not organised on a permanent or community basis. The Data Terra repository ( is ideally suited to the storage of such data. Atmosphere domain data is moderated by AERIS.
For example, you can quickly obtain an identifier for publication. It will still be possible to use the data a posteriori via the call for projects. As a reminder and for information, the applicant is responsible for the quality and origin of the data. The AERIS office will inform the Scientific Council and the AERIS Steering Committee of the data deposited in the repository. However, in case of doubt, the office reserves the right to ask the AERIS Scientific Committee for an opinion before approving or rejecting a submission.

The Open Science approach

At the AERIS Board meeting on 24 January, the supervisory bodies (CEA, CNES, CNRS, Ecole Polytechnique, IGN, IRD, Météo-France, Région Hauts-de-France, Sorbonne Université, Université Lille-1, Université Paul Sabatier) reiterated their commitment to open science and the rules that go with it.
Everyone agrees (CNRS recommendation) to accept an embargo (maximum 2 years) to allow quality assurance on the data and/or publication work that could justify not making the data public immediately.
However, if the data is not accessible for reasons of embargo, there must be information on the project website and/or its catalogue indicating the list of data and the planned date of its release (date of end of embargo).
For information or a reminder:

  • Data under embargo may appear in your project’s catalogue and that of AERIS without the data being accessible outside authorised persons whom you define.
  • Your data can then be “found”, you can receive access requests, and develop new collaborations that will lead to publications and the exploitation of your data.
  • You can (and should) attach a user licence to your data to limit its use by third parties. AERIS can advise you on the choice of the appropriate licence.
  • Visuals (such as quicklooks) cannot be considered as embargoed data and should be made public quickly.
  • A unique identifier (such as a DOI) is now an effective way of tracing the use made of the data.

Finally, for those who fear that their data is being misused, we would like to reassure them that no such report has ever been made to AERIS (and before that to Ether and ICARE). We do, however, have a good list of examples of shared data that have led to new studies and publications involving the data PI.
