Project Description

The 4D Greenland project aims to perform an integrated assessment of Greenland’s hydrology through maximizing the use of Earth Observation data.  This is done through quantification of the major components of Greenland’s hydrological system and their interconnections: surface melt processes, supraglacial dynamics, and subglacial melt, storage, and drainage.

The large ice sheets play a vital role in the Earth’s climate system, but they are sensitive systems that are notably susceptible to climate. Understanding the hydrology of the Greenland Ice Sheet is essential to gain insight into these changes and how the ice sheet changes will affect local and regional ecosystems and contribute to global sea-level rise in a future warming climate.
