Ridgepack is a MATLAB sea ice model analysis and development package designed as part of the Regional Arctic System Model (RASM) project, funded by the Department of Energy, Office of Naval Research, and National Science Foundation. It is used primarily to analyse output from RASM and the Community Earth System Model (CESM) sea ice components, and for model developments leading to contributions to the CICE Consortium sea ice model (https://github.com/CICE-Consortium).
This is a library of MATLAB functions to read netCDF data output from CICE and make vigorous use of the metadata within the output to aid model analysis. The library also contains development libraries for new physics being implemented in the RASM sea ice component. There are currently four libraries:
datastructures - ingesting, twisting and turning and outputting CICE data
graphics - publication quality graphics functions for CICE
infrastructure - basic infrastructure for Ridgepack to operate smoothly
morphology - library of sea ice thickness distribution functions
The cases area of Ridgepack is designed for MATLAB scripts that make use of the above function library. Currently there is one set of case scripts available to accompany a publication under review:
JAMES_2018_Variational_Ridging - Scripts used to demonstrate the functionality of the sea ice morphology library described in: Roberts, A.F., E.C. Hunke, S.M. Kamal, W.H. Lipscomb, C. Horvat, W. Maslowski (2018), Variational Method for Sea Ice Ridging in Earth System Models, Part I: Theory, submitted to J. Adv. Model Earth Sy..
A second case will be released in 2018:
RASM_Sea_Ice_Toolbox - Scripts used to analyse the dynamics and thermodynamics of the coupled RASM sea ice component.
This is a sample MATLAB startup file to accompany Ridgepack, and includes examples of setting several environment variables relevant to this MATLAB utility. It is anticipated that MATLAB will be run on a Unix, Linux or Mac OSX platform when using this package.
