Plastic damage in sea ice - model outputs and observations.

<p>Sea ice model outputs and observations analyzed in the paper: "On the sensitivity of sea ice deformation statistics to plastic damage".</p> <p>For the outputs, there is one file every 6 hours (for January 2002). Each folder represents one experiment with the associated snapshot files each containing a matrix of the given variable.</p> <p>The observations are the 3-day gridded velocity derivatives. The files are numpy arrays (.npy) containing time slices for every 3-day period for January 2002.</p> <p>&nbsp;</p> <p><strong>1. Naming convention of the files</strong></p> <p><em>Model outputs</em></p> <p>The folders are named according to the model configuration following the names used in (Savard and Tremblay, 2024):</p> <p>"Model name" + ( + "configuration" + )</p> <p>The files in each configuration follow the following convention:</p> <p>"Variable" + "year" + _ +&nbsp; "month" + _ + "day" + _ + "hour" + _ + "minutes" + . + "experiment number"</p> <p>There is also an info file, which provides the numerical parameters used in each run:</p> <p>info + . + "experiment number"</p> <p><em>Observations</em></p> <p>The files are the velocity derivatives:</p> <p>"partial derivative" + .npy</p> <p>There is also a mask for the period of January-February-March:</p> <p>mask80JFM.npy</p> <p>&nbsp;</p> <p><strong>2.
