PRODEM: Annual summer DEMs of the marginal areas of the Greenland Ice Sheet

Surface topography across the marginal zone of the Greenland Ice Sheet is constantly evolving in response to seasonal variability, longer-term climate change, and glacier dynamics. Yet, current Digital Elevation Models (DEMs) for the ice sheet are usually based on data from a multi-year period, thus obscuring these changes over time. PRODEM is an annual series of summer DEMs in 500-meter resolution of the ice sheet marginal zone, a 50km wide band covering all outlet glaciers of the Greenland ice sheet. The annual summer DEMs follow the naming convention PRODEMyy, with yy being the year. The data series starts in summer 2019, and the product is expected to be updated annually over the coming years.
