C2 Snow-On-Seaice Improvements

C2 Snow-On-Seaice Improvements

This page is a main, parent documentation page for this feature. The tables below provide links to all related documentation on this feature. 

The first Dependencies Table provides information on features dependencies, lists expected Pull Request (PR) date (expected time this feature will be ready for integration), it also lists all the other known new code features that are blocking completion of this code. It lists all known features that depend on this feature being integrated. It also provides the date the PR was actually issued, the name of the integrator, the date the code was integrated and a hash/tag of the code integration into the ACME git repository. The information from this table feeds the overview table in the New Features Dependencies Overview page which is meant to be used by integrators to check the priority order in which the features should be integrated. It also provides an overview of all the new features and the expected integration dates. 

The second Checklist Table lists the code review steps to be taken in order. As you work on integrating your feature into ACME code, step along the Checklist table on your main page, obtain the approvals before going to the next step. For the phase 1 review, the Group Leads are the approvers, they can decide to sign on on the documentation or a verification step even if it is not completely finished, especially for the grandfathered features. The relevant documentation page does have to be created though and the explanation needs to be provided in Summary section as to why it is approved, what is the basis for approval. For example is there were tests performed on related feature and they proved indirectly that this feature works as expected, then the approver needs to document that. 

The Design Document page provides a description of the algorithms, implementation and planned testing including unit, verification, validation and performance testing. 

The Verification and Unit Testing page provides the short information and links to the tests that were performed, together with the links to the runs, their provenance and their results. The same information is called for in The Performance Assessment page and The Validation page in phase 1 of code review process.

Note that these physics are currently off by default. Deciding whether or not to turn them on by default for v2 will require additional testing / tuning / validation as part of the fully coupled system.
