Arctic+ Ice

Estimating sea ice mass balance

Arctic+ Ice

Towards a reconciled estimate of Arctic sea ice mass.

The main objective of this project was to derive a reconciled estimate of Arctic sea ice mass balance using data from the most advanced, recent EO missions, namely ESA’s ERS, Envisat, CryoSat and SMOS missions and NASA’s ICESat mission, and state-of-the-art numerical models. Numerous processing methods have been developed and estimates of seasonal and interannual ice volume changes have been published. We have collected these different data sets and applied unified methods when converting freeboard to thickness and then mass over consistent regions and time periods.

The project has allowed to explore, develop and validate different approaches to improve sea ice mass estimates and their application; to develop a new prototype processor, and to produce and validate an experimental dataset of improved, multi-product Arctic ice thickness, volume and mass.
