IMBIE, or the Ice sheet Mass Balance Inter-comparison Exercise, was established in 2011 as a collaborative initiative aimed at reconciling satellite measurements related to ice sheet mass balance. With support from notable organizations like the European Space Agency (ESA) and NASA, IMBIE plays a crucial role in diminishing the uncertainties associated with ice sheet mass balance estimations. The initiative focuses on integrating diverse satellite techniques—altimetry, gravimetry, and the input-output method—to generate more accurate assessments of ice sheet contributions to global sea level rise.

As an essential resource for the Intergovernmental Panel on Climate Change (IPCC), IMBIE not only enhances confidence in measurements but also provides vital data to a broad array of stakeholders concerned with climate change impacts. The organization actively encourages participation from the global scientific community, ensuring a comprehensive approach to studying and mitigating the effects of climate change on sea levels. Through its ongoing efforts, IMBIE seeks to contribute significantly to our understanding of ice sheet dynamics and their implications for future sea level projections
