NA3 (WP4): Earth System Modelling Environments

Objectives


The objective of this work package is to provide networking activities to increase the pace of climate science employing modelling by sharing best practice in software environments for Earth System Models and encouraging more sharing of selected codes within the climate community.

Scientist using Earth System Models (ESMs) not only need access to models, but also a rich environment of tools to support these models. This software environment includes: (i) Workflow tools to manage the increasingly complex series of tasks required to run ESM experiments and seasonal to decadal prediction systems; (ii) Post processing tools to analyse ever increasing volumes of data in a way that can be used consistently between models and across scientific disciplines; (iii) Configuration management tools to manage scientific model and technical codes as well as experiment definitions effectively; (iv) Meta-data capture tools to ensure that the experiments, simulations, and data are properly described and governed and (v) Coupling tools to ensure scientific component models can be combined to provide more comprehensive ESMs.

Networking will lower the following barriers for the use of common software solutions for workflow and post processing (task 1), configuration management (task 2), meta-data capture (task 3) and coupling (task 4):

  • Technical and human resources in most institutions are stretched and often applied to extend existing legacy solutions rather than to take the more risky approach of trying new solutions. Also, developments are targeted at local problems. Even when they have the potential to find more generic application, they are not advertised as such and are not used more widely. This work package will provide opportunity for advertising solutions to a wider community by sharing experience in software that deals with the modelling environments.
  • The lack of understanding of longer-term benefits of available solutions. If some participants are able to quantify the benefits of apparently risky or large changes, other participants are more likely to invest thus spreading best practice. The large overheads of software evaluation in this field. Any software needs to be adapted to meet specific, complex local needs. This work package supports evaluations of software for all the ESM environment tools listed above..

 

For all tasks 1 to 3, the objective of this work package is to facilitate best practices and software sharing by supporting software evaluations that will lead to well prepared, in depth workshops allowing partners to understand the opportunities for shared software solutions.   It will fund teams to evaluate software and effort to support the evaluators. This bottom-up approach will be complemented by the management engagement proposed in NA1. Furthermore, a focus on the governance of the coupler development in the community is now required, task 4 will deal with this issue and provide hints for the governance also of other shared software initiatives.

Deliverables

 

D4.1 Configuration management initial workshop report_revised version

The FCM configuration management system and processes around it are now widely established across a wide number of projects at the MetO and is a potential candidate for wider sharing in the climate community. Although CNRS-IPSL uses parts of FCM, they do not access its full functionality. The workshop report will provide recommendations on opportunities for wider uptake of FCM or alternative approaches for sharing best practice if these are found.
