SA1 (WP7): The European Network of geographically distributed services on Earth System models, component models and tools

Services currently offered by the infrastructure:


All services on ESMs, components and tools will be available through the ENES portal operated by DKRZ (see WP2/NA1), previously known as the “vERC” portal in IS-ENES1. At the start of IS-ENES2, SA1 includes the service on OASIS, CDO and NEMO accessed through their websites as well as the European ESM documentation and CIM metadata description available through ENES portal. During the course of IS-ENES2, these services will be maintained and updated as well as the service on ESMs set.

Services on ESMs

The 7 European ESMs groups have reached different levels regarding the provision of services around their ESM. During IS-ENES1, documentation of the European ESMs participating to CMIP5, under free format and in the form of metadata organized in a new conceptual model called the Common Information Model (CIM), has been gathered (more detailed information here). Under IS-ENES2, this documentation will be maintained and extended. Furthermore, the network of experts that started to be organised around the European ESMs in IS-ENES1, with a contact person identified for each ESM for the cases where local expertise is needed beyond the available documentation, will be reinforced. In IS-ENES1, an ESM evaluation portal providing a searchable database on datasets and variables used for Earth System Model evaluation was assembled and access to this evaluation portal will be maintained in IS-ENES2.The 7 European ESMs are in constant evolution, benefiting from state-of-the-art numerical science; during IS-ENES2, some of them will be implemented and run at higher resolution than the ones used in CMIP5 (see JRA1 Task1) and some of them will serve as a basis for IS-ENES2 JRA2 benchmarking.


The seven European ESMs are described in the IS-ENES2 Description of Work. Here are some specific details about their user community and access rules when applicable (Levels 1 and 2 are defined in task 2):

  • Met Office Unified Model ESM (installation 1, ESM Level 2, MetO): The services will target different versions of the Unified Model and in particular the Hadley Centre climate configurations HadCM3, HadGEM2-AO and -ES and HadGEM3-AO. Around 40 organisations are licensed to use the Unified Model (UM) for non-commercial research activities (UK and international academic organisations in Argentina, Canada, India, Korea, Australia, and South America), and 7 organisations are licensed to use the Unified Model for operational activities. Non-commercial research licences are provided in exchange for an abstract detailing the research to be carried out.
  • EC-Earth (installation 2, ESM Level 2, KNMI, SMHI): EC-Earth is available to all ECMWF member states and cooperating members (currently 34 countries) without financial commitment, as long as they show intention to work with the EC-Earth consortium.
  • IPSLESM (installation 3, ESM Level 1, CNRS-IPSL): IPSLESM is available in different configurations at different resolutions. 80 users, coming from CNRS-IPSL and associate laboratories, are registered while about 200 persons use one or more components separately. It is evaluated that more than 550 projects access IPSLESM IPCC result database.
  • NorESM (installation 4, ESM Level 1, UiB, NorESM is used at UiB and in the framework of CMIP5. Explicit permit is needed to use NorESM to make sure that potential IPR issues are correctly handled also with respect to the NCAR routines incorporated in this model.
  • C-ESM (installation 5, ESM Level 1, CMCC): C-ESM was set-up and used by CMCC for their participation in CMIP5.
  • MPI-ESM1 (installation 6, ESM Level 1, MPG): MPI-ESM1 is the full Earth System Model developed by MPI-M, used for their contribution to CMIP5. About 45 different research groups around the world currently use this model.
  • CNRM-CM5 (installation 7, ESM Level 1, MF-CNRM): The atmospheric component of CNRM-CM5, ARPEGE, is available for the scientific community with an exclusive aim of research, within the framework of the “Community Climate Model” project.

Services on NEMO ocean components

Particular services offered around the NEMO ocean component model in IS-ENES1 (see here) will be pursued and extended. NEMO is the ocean component model used in 5 of the 7 European ESMs and also used in stand-alone mode in many oceanographic studies. Overall, NEMO is currently used in 240 projects in 27 countries (14 in Europe, 13 elsewhere) and has more than 350 registered users.  The NEMO reference database assembled during the IS-ENES1 project will be maintained and enriched with new experiment produced with higher resolution reference configurations. This reference database, which leverages NEMO User Guides, will help the large community of NEMO users to better evaluate the validity of their oceanic simulations.

Services on ENES community tools

Expert services will also be available for the most important community tools developed and used in ENES, i.e. OASIS and CDO. Services on these tools have already started in IS-ENES1 and their further development is actively going on in IS-ENES2 (see JRA1 Task 2 for OASIS and JRA1 Tasks4 for CDO).

The OASIS coupler software allows synchronized exchanges of coupling information between numerical codes representing different components of the climate system; OASIS3 is currently used by approximately 30 climate modelling groups in Europe, USA, Canada, Australia and Asia.


CDO (Climate Data Operators) is a collection of about 100 functions for handling and analysing data produced by a variety of climate and NWP models - e.g. for file operations, simple statistics, or the calculation of climate indices. The code is used by around 150 groups (220 users) world-wide, including some of the project partners, calling the CDO around 200000 times per day.


The web services (e.g. on-line download, installation information, tutorial, FAQs, hints for best practices) for the OASIS3 coupler (see here) and the CDO processing tool (see here) set up during IS-ENES1 will be maintained and further developed to support their always growing community of users.
