Description

With the aim of using machine learning as a tool to predict and understand sea-ice motion in the Arctic on one-day timescales, these data include processed satellite and reanalysis measurements of sea-ice velocity, sea-ice concentration, and wind velocity. Also included are outputs from statistical model predictions. Finally, we include all files required to download and process raw data, run statistical models, and plot analyses of outputs.

Maps showing the performance of a machine learning model built to predict sea-ice motion in the Arctic. (Left) A convolutional neural network (CNN) makes skillful predictions of sea-ice motion in the Arctic, where lighter colors are indicative of a higher predictive skill in the map of the first panel. (Right) A CNN typically outperforms a traditional linear regression (LR) model in predicting Arctic sea-ice motion, where red is indicative of areas where the CNN outperforms LR in the map of the second panel.
