Extended Data Fig. 2

The blue circles represent the MODIS time series after cloud removal and median filtering. The red line represents the detected breakup date, defined as the mid-point of the first day when the grid cell contains greater than 90% water and the previous observation. The grey-shaded region represents the uncertainty due to cloud cover.
