Antarctic and Greenland Ice Sheet mass balance 1992-2020 for IPCC AR6
This dataset contains rates of mass change and cumulative mass change and their associated uncertainty for the Antarctic Ice Sheet (in its entirety and split into West Antarctica, East Antarctica and the Antarctic Peninsula), the Greenland Ice Sheet, and their sum between 1992 and 2020. The data are reconciled estimates of mass balance from three independent satellite-based techniques: altimetry, gravimetry and input-output method. This dataset is part of the Ice Sheet Mass Balance Intercomparison Exercise (IMBIE).
This work is an outcome of the Ice Sheet Mass Balance Inter-Comparison Exercise IMBIE) supported by the ESA Climate Change Initiative and the NASA Cryosphere Program. Andrew Shepherd was additionally supported by a Royal Society Wolfson Research Merit Award and the UK Natural Environment Research Council Centre for Polar Observation and Modelling (cpom30001).

Methodology:
The data used to produce this reconciled mass balance estimate were gathered in the framework of the IMBIE project. In total, 46 independent satellite estimates of mass change (21 Antarctica, 25 Greenland) were used to produce this final dataset. The methodology to aggregate these into a final estimate are described in both Shepherd et al (2018) and Shepherd et al (2019).
Data collection:
Each dataset contributed to the IMBIE project was processed independently by their contributors and the methods and errors on their dataset have been documented in an international peer-reviewed journal. A dedicated processor was developed in Python to compute the reconciled mass balance estimate and its uncertainty, and the core code is freely available at https://github.com/IMBIE.
Data quality:
The data are reconciled estimates from 46 individual satellite-based surveys derived from the altimetry, gravimetry and input-output techniques. The respective one sigma uncertainties for each reconciled dataset are provided.
