Presentation Transcript

  1. ESGF and ES-DOCDocumenting climate models and their simulations Eric Guilyardi, Balaji, Cecelia DeLuca, Sébastien Denvil, Mark Greenslade, Bryan Lawrence, Sylvia Murphy, Karl Taylor + ES-DOC current and future plans Working with ESGF = ESGF & UV-CDAT meeting, Livermore - December 2013

  2. Why ES-DOC • Document underlying science in climate models and whys and hows of simulations (forcing, protocol, …) • Understand differences and similarities in multi-model ensembles • Use of climate model data expanding • Maturity and openness of model development • Essential building block of professional documentation (with CF, DOI, …) • Legacy joint venture of METAFOR (EU) and CURATOR (US) projects • Guilyardi et al. (BAMS 2013)

  3. ES-DOC = creation, exploitation and dissemination of standards • Climate modelling metadata conceptual model: the Common Information Model (CIM) -> ConCIM (UML) • Real life application: CMIP5 -> AppCIM (XML) • Questionnaire, database, CIM tools (viewer, comparator) • Definition of controlled vocabulary (CV) • Part of CMIP standards • Governance of standards

  4. TheCONCIMtoAPPCIM UML Conceptual Model Climate Modelling = an activity using a software to produce data on a grid to be archived in a repository. e.g. CIM XSD Application Model Application Model e.g. CMIP5 RDF XML Instance @ BADC An essential aim is that the conceptual model is not changed by the manner in which it is used or applied. Instance @ IPSL Instance @ PCMDI

  5. ControlledVocabulary Novelty in community: Software CV Creating the CV mindmap Gathering a way of describing (in a community consistent way) the scientific properties of model subcomponents 570 controlled questions - hundred of choices !

  6. cf. Mark Greenslade presentation Thursday

  7. ES-DOC and CMIP5 metadata status • What we have today: • The CIM: strategic community effort effort here to stay, several projects already leveraging from it • CMIP5 documentation: 42 models and 600 simulations described in CIM database – a unique ressource – contributes to AR5 (model table), articles… • A set of controlled vocabulary • CIM tools:viewer and comparator (web service) • Governance: ES-DOC. EU-US close collaboration, management and development process • Community « education » that such efforts contribute to scientific process, credibility of projections and showcase of climate models

  8. Next steps and challenges • CMIP5 database quality control • Role of model development groups vs. role of users (e.g. annotation) ? • Governance of CIM and CV • Extension of scope (downscaling, …) • CIM tools ecosystem development • Prepare CMIP6: • Core and tier 1 documentation ? • New generation of capture tool, better separation of concerns • Quality control, peer-review, DOIs • Sustained funding on top of « ad-hoc » institutional funding and projects (IS-ENES2, PIMMS, ex-Arch,…)

  9. Working with ESGF • Coherence of data/metadata structure and contents (e.g. 8 realms not useful for IPCC report) – via CMIP or new data panel ? • ESGF/ES-DOC human and technical coordination • For development and operations • On web services, new ESGF deployments include metadata checks, etc… • How do we organise coordination for CMIP6 ? • Similar governance and funding challenges
