NA3/WP4 Strengthening the European Network on Earth System Modelling


Objectives

 

Numerical modelling is the most appropriate approach to study and experiment with the Earth climate. The most sophisticated Earth System Models (ESMs) today include components representing the ocean including its biogeochemistry, the atmosphere with its chemistry and aerosol microphysics, the sea-ice, the land and its vegetation. In Europe, different ESMs (some of them only in the form of ocean-atmosphere Coupled General Circulation Models (CGCM)) are being developed by different climate research groups (see Appendix 1). Fortunately, those groups already share today some software tools and component models becoming “de facto” standards for the benefit of the whole community. The 2 common software tools identified are the OASIS coupler and the CDO processing tool, while NEMO is an ocean component model used by a large majority of partners in the project (see Appendix 2). Strengthening even further the scientific and technical interactions between those groups is today essential, as the individual groups are no longer capable of mastering the entire complexity of the system.

In this respect, IS-ENES will establish standardized information about existing ESMs in Europe. As each ESM is a complex system gathering components that can be configured in different ways with different parameter values, a proper and standard-compliant documentation of ESMs is absolutely essential to ensure the full exploitation of the results not only by their developers, but also by other scientific groups in the community. The Common Information Model (CIM) developed in the METAFOR project that proposes a standard way to document climate models will be used.

IS-ENES will also promote the use of the “de facto” standard software tools and component model by helping the groups developing those tools to integrate community developments and to set-up the services around those tools that will be offered in SA1.

Progress

The WP activity is satisfactory with a good implication of the different groups developing ESMs in Europe and with the OASIS, CDO and NEMO developers providing active user support and networking on their respective software.

Task 1: ESM documentation:

This task is progressing well with deliverable D4.1 “ESMs current documentation, including a description of associated tools and specific Assembling Guide” ready on time for all ESMs (except for HadGEM2-ES from the METOFFICE -see “Deviation” paragraph below).  The deliverable D4.2 “ESM documentation following a subset of CIM metadata” due at month 18 has been delayed by 6 months to allow the groups to fill in the METAFOR CMIP5 questionnaire that will automatically produce the ESM description following a subset of CIM metadata.

Task 2: Networking on common tools and components:

This task, which concerns OASIS, CDO and NEMO, is taking place satisfactorily. The constantly growing OASIS community receives day-to-day general support through emails.  More specific support has also been provided through 2 training sessions and 3 on-site visits as planned. For CDO, networking is well promoted by the set-up of a new website and web-based community interface. For NEMO, user support and integration of developments are realized on a regular basis. Furthermore, the design of a reference simulation and the realization of the corresponding experiments have started.

 

Deliverables

D4.1 - ESMs current documentation, including a descritption of associated tools and specific "assembling guide"
D4.3 - OASIS complete web site accessible via the v.E.R.C. portal (WP3)
D4.5 - web NEMO configurations database filled up by NEMO team
