Short summary
Measuring sea ice thickness is difficult using satellite data, but it is crucial for understanding climate change. This study introduces a new method that estimates ice thickness by tracking where and when sea ice formed and calculating how much it likely grew based on daily weather conditions. The results agreed well with underwater measurements. This method helps map ice thickness across the Arctic and may support estimates of other hard-to-measure sea ice features.
