CORDEX-CMIP7 Archiving Specifications for Dynamical Downscaling

Under Development

This document is currently under development. The specifications described here are preliminary and subject to change.

Status

The CORDEX-CMIP7 archiving specifications for dynamical downscaling are being developed to align with:

  • CMIP7 data standards
  • Updated ESGF infrastructure
  • Latest CF Conventions
  • Community feedback

Preliminary Scope

When complete, this document will provide specifications for:

  1. DRS elements: Updated data reference syntax for CORDEX-CMIP7
  2. Global attributes: Required NetCDF metadata
  3. File naming conventions: Standardized file naming patterns
  4. Directory structure: ESGF publication directory layout
  5. File format: NetCDF format and compression requirements
  6. Coordinate systems: Grid definitions and coordinate variables
  7. Time handling: Time coordinate and calendar specifications, file granularity, ...
  8. Registration: Institution and model registration procedures

Timeline

The development timeline for CORDEX-CMIP7 archiving specifications will be coordinated with:

  • CMIP7 timeline and milestones
  • CORDEX community discussions
  • ESGF technical readiness

Feedback

Community input is essential for developing robust specifications. To contribute:

  • Open issues at GitHub Issues
  • Participate in open issues/discussions
  • Review and comment on draft specifications when released
