Welcome to the Icepack wiki!
This repository contains the Icepack sea ice column physics code, which has been split out from the CICE sea ice numerical model. CICE includes Icepack as a git submodule.
Code documentation is included within each code repository, and links to data and other information can be found on the wiki pages of each repository.
Prior release info is linked from https://github.com/CICE-Consortium/CICE/wiki
Comprehensive information about the current version of Icepack is found in the online and searchable documentation, including a "Quick Start" section, a science guide, a user guide, and a developer guide. Note that the Table of Contents can be accessed at any point by clicking the upper left hand "Icepack 1.0 documentation" link.
Icepack Documentation
CICE Git Workflow Guidance (includes instructions for working with Icepack)
The About-Us repository and wiki contain additional information, including contact information and instructions for code developers.
To port Icepack to your machine, you may do the following:
- Install external software.
- a Fortran compiler
- gnuplot is needed only for visualization of test results using the script in Icepack
- Download Icepack. We recommend using github to interact with the Consortium; other download options are listed in the README.md file.
- fork the Icepack repository
- clone the code as described in the CICE Git Workflow Guidance
- Follow instructions as in the "Quick Start" section of the documentation.
- Download and untar the forcing data to the location defined in the scripts (ICEPACK_MACHINE_INPUTDATA in the env file), for basic testing.
Icepack is also downloaded automatically when CICE is cloned. We recommend making changes to Icepack via a separate repository rather than using the version linked as a CICE submodule, unless changes to CICE must also be made concurrently. See the CICE Git Workflow Guidance.
More detailed information is available on the Testing-Icepack page including information about setting up standard tests (e.g. regression, restart) and obtaining near-surface forcing data is found here.
A community bulletin board has been set up for the CICE-Consortium community to discuss model development including bugs, diagnostics, and future directions. There are subforums for discussion of particular topics (e.g. repository questions) as well as a general forum. These forums will be monitored by consortium members but are open to the general community. To start or respond to a discussion topic users will need to create an account by clicking the "Login" button at the top of the page and then following the directions under "Create new account."
