Model output: CICE6-WIM Antarctic sea ice data (2010--2019)

CICE6 model with waves-in-ice module (WIM) output analysed with k-means clustering to identify the Antarctic marginal ice zone. Daily data at a 1-degree horizontal resolution of the variables used to inform k-means and the physical processes which drive the Antarctic marginal ice zone are included. The model was spun-up over 2005–2009 and outputs were analysed over 2010–2019. For further details, see Day, N. S., Bennetts. L. G., O'Farrell, S. P., Alberello, A., & Montiel, F. (2023) Analysis of the Antarctic Marginal Ice Zone Based on Unsupervised Classification of Standalone Sea Ice Model Data. Data files: iceh_{year}.nc: gridded NetCDF files containing the training variables for k-mean clustering and the fitted clusters. forcing_variables_2010_2019.csv: flat file containing variables of CICE6-WIM forcing and sea ice dynamics. fsd_processes_2010_2019.csv: flat file containing each term of the prognostic floe size distribution model in CICE6.
