Short summary

We developed a new statistical approach to track monthly changes in the surface height of the Greenland Ice Sheet using radar data from the CryoSat-2 satellite (2011–2025). The method lets seasonal and long-term variations emerge directly from the data, creating a consistent record of elevation change that helps reveal how Greenland responds to ongoing climate change.
