Create a Land Model Benchmarking Capability for ACME

Requirements and Design

ACME

Summary

The purpose of this section is to summarize what capability is to be added to the ACME Ocean and Ice system through this design process. It should be clear what new code will do that the current code does not. Summarizing the primary challenges with respect to software design and implementation is also appropriate for this section. Finally, this statement should contain general statement with regard to what is “success.”

 A land model benchmarking package will be implemented, leveraging the ongoing ILAMB development in the RGCM-funded BGC Feedbacks SFA, for routine and systematic assessment of land model fidelity through comparison with observational data. Initially, a recent version of the ILAMB prototype will be installed and tested using ACME Land Model (ALM) output. New model–data comparisons will be added by the team of ACME benchmark developers for evaluating the impact of new feature implementation on the overall scientific performance of ALM in coupled and uncoupled configurations. The Workflow Team will be encouraged to adopt this evolving benchmarking package for operational use for evaluating relevant contemporary land and Earth system model simulations.

Requirements

Requirement: name-of-requirement-here

Each requirement is to be listed under a ”section” heading, as there will be a one-to-one correspondence between requirements, design, proposed imple- mentation and testing. Requirements should not discuss technical software issues, but rather focus on model capability. To the extent possible, require- ments should be relatively independent of each other, thus allowing a clean design solution, implementation and testing plan.

 

Algorithmic Formulations

For each requirement, there is a design solution that is intended to meet that requirement. Design solutions can include detailed technical discussions of PDEs, algorithms, solvers and similar, as well as technical discussion of performance issues. In general, this section should steer away from a detailed discussion of low-level software issues such as variable declarations, interfaces and sequencing.

 

Design and Implementation

This section should detail the plan for implementing the design solution for requirement XXX. In general, this section is software-centric with a focus on software implementation. Pseudo code is appropriate in this section. Links to actual source code are appropriate. Project management items, such as svn branches, timelines and staffing are also appropriate. How do we typeset pseudo code?
