Analysis Platforms for CMIP6 and CORDEX

last modified Sep 21, 2019 10:35 AM
Trans-national Access (TNA) First Call





Apply for virtual workspaces and directly access compute facilities

with locally maintained CMIP and CORDEX data pools

without the need of downloading model data

First Call Opening: 16 of September 2019 - Deadline: 31 of October 2019


The climate modelling community faces the challenges of contributing to the next assessment report of the Intergovernmental Panel on Climate Change through the 6th phase of the Coupled Model Intercomparion Project CMIP. The ENES e-infrastructure project IS-ENES3 H2020-INFRAIA addresses these challenges by developing, documenting, and deploying new and advanced models and tools, standards and services to deal with unprecedented data volumes and model complexity. 

IS-ENES3 stimulates collaboration and facilitates hardware, software, and data share. Data near processing capabilities at the centers CNRS-IPSL, CMCC, DKRZ, and UKRI STFC-JASMIN (see the specific technical description below) will be made accessible to a broader user community from 16-09-2020 via the new Trans-national Access (TNA) service.

These processing capabilities support multi-model server-side data analyses through direct access to large data pools including replicated data from the European as well as non-European ESGF data nodes. An evaluation committee will supervise the selection of applications for virtual workspace access. Results from user groups enabled through the virtual workspaces access will be disseminated under the project.

  • Available data pools

With this new service, users will not need to download the data because the analyses will be performed at the host server. There are several ways to find wich access provider hosts the data of your interest. The specific variable-centric collections can be browsed at any ESGF portal: find the project you are interested on (CMIP6, CMIP5, or CORDEX) in the "Search Data" section in the portal home, it will land in a faceted search, then click on "Show replicas" and select the provider in the "Datanode" display:  

- vesg.ipsl.upmc.fr to see the CNRS-IPSL data pool

- esgf-node.cmcc.it to see the CMCC data pool

- esgf1.dkrz.de, esgf2.dkrz.de, and esgf3.dkrz.de to see the DKRZ data pool

- esgf-data1.ceda.ac.uk, esgf-data2.ceda.ac.uk, and esgf-data3.ceda.ac.uk to see the UKRI STFC-JASMIN data pool.

and then click on "Search". If you prefer to see the THREDDS catalogue, find the data pool URLs for the CNRS-IPSL, CMCC, DKRZ, and UKRI STFC-JASMIN (at CEDA) here.

Data and resources are continuously updated. The complete data pool might be in the process of being published at the ESGF portals. Two access providers have their own browser, please visit the DKRZ catalogue and the STFC-JASMIN catalogue. Data that are not already at the access provider's pool can be replicated on demand at any provider, please see the descriptions below.

  • Timeline of the First Call

New calls will be opened every six months and the following relevant dates will be updated here:

    • Deadline for applications: 31.10.2019. If you miss the deadline, please, apply to the next call before the 30.04.2020

    • Evaluation time ~ 1 month01.11.2019 - 30.11.2019

    • Selection/Assignment time ~ 2 weeks → 01.12.2019- 14.12.2019

    • Start of 1st service period: → 01.01.2020

    • Service duration per user ≤ 6 months

  •  Evaluation
    • Committee member's expertise cover:
      • Climate model evaluation, including process studies
      • Using climate model output to drive impact models
      • Using statistical and dynamical downscaling to assess information at finer scales.
    • Priority will be given to new users and users from countries with no equivalent research infrastructure.
    • The climate impact community is encouraged to apply.
    • IS-ENES3 enforces an equal opportunities evaluation process.
    • The call is mainly for EU or associated countries. Up to 20% of the access can however be dedicated to non-EU or associated countries (the units of access are the CPU hours, please, check above the technical features per center).
    • Selection Criteria

      • Fit to ENES objectives (see more here):

        • Integration of the Earth's climate system modelling community and the sustainability of its infrastructure.

        • Common development of models and tools, and the efficient use of HPC.

        • Exploitation of model data by the Earth system science community, the climate change impact community and the climate service community.

      • Appropriate use of resources: proposals should demonstrate awareness of the advantages of the infrastructure that they wish to use; they must explain how their project will exploit the infrastructure. They should explain level of resources they need, and clearly justify the use of these resources.
      • Scientific Excellence: projects should demonstrate good understanding of scientific issues in their chosen domain, and the ability to develop excellent science through their work-plan.  Ideally, reference should be made to the WCRP Grand Challenges.
      • Project Management: proposals must set out clear objectives and a well structured timetable, with appropriate milestones, for project execution. Measures to quantify the success of the project in meeting these objectives should be defined (e.g. data sets published, conference proceedings, scientific literature). As IS-ENES3 is not covering any investigator staff costs, projects must demonstrate that they have the resources necessary to exploit infrastructure allocations.


  • Please, keep in mind that data and resources are continuously updated. Please, check regularly our FAQs section, we will include there the relevant news.
