This section outlines the steps for testing and integrating newly developed code into the existing sea ice model. This procedure has been designed to ensure that new code meets CCSM and CSIM requirements and improves the climate simulation and/or the model performance. All substantial code changes must go through the Polar Climate Working Group (PCWG) review process. Substantial refers to all physics changes and any software engineering changes that result in major changes to code organization and/or efficiency. This generally does not include cosmetic changes to the code.
It may not be possible or necessary for a developer to carry out all of the steps
described in this section. For most development, it will be necessary to
contact the liaison or a co-chair of the Polar Climate Working Group. This
information is on the PCWG web page:
The PCWG review process will usually involve the following steps:
