 An Introduction to CIME

Abstract: 
CIME (pronounced "seam") is a collection of infrastructure utilities that is comprised of several distinct categories:

  1.  A Case-Control-System to support user friendly workflows including configuration, compilation, execution, system testing and unit testing of an earth system model

  2. Coupled model architectures (including the new ESMF/NUOPC Community Mediator for Earth Prediction Systems)

  3. Data models that can be swapped for prognostic components and enable hierarchical model development

  4. Source code for external libraries useful in scientific applications (e.g. PIO)

  5. Additional stand-alone tools.

CIME is available in a stand-alone package that can be compiled and tested without active prognostic components but is typically included in the source of compatible Earth System Models. CIME is developed in an open-source, public repository and has been jointly developed by both NCAR/CESM and DOE/E3SM.

In this talk an overview of CIME will be given, focusing in particular on the workflow capabilities of the Case Control System.
