MAR projections of the Antarctic surface mass balance over the 21st century (ACCESS1.3)

This archive provides daily outputs of the Antarctic Surface Mass Balance over the 21st century as simulated by the RCM MAR forced by ACCESS1.3 (CMIP5, rcp8.5).

These outputs, as well as MAR forced by other models, were produced as part of the publication "Diverging future surface mass balance between the Antarctic ice shelves and grounded ice sheet", accepted for publication in The Cryosphere (https://doi.org/10.5194/tc-2020-291)

Data usage notice:

If you use any of these results, please acknowledge the work of the people involved in producing them. Acknowledgements should have language similar to the below that contained both informations related to MAR and CMIP5/6. In order to document MAR scientific impact and enable ongoing support of the model, users are likely encouraged to contact C. Kittel to add their works in the list of MAR-related publications. 

"We thank C. Kittel and the MAR team which make available the model outputs, as well agencies (F.R.S - FNRS, CÉCI, and the Walloon Region) that provided computational resources for MAR simulations. We acknowledge the World Climate Research Programme, which, through it's Working Group on Coupled Modelling, coordinated and promoted CMIP5 and CMIP6. We thank the climate modeling groups for producing and making available their model output, the Earth System Grid Federation (ESGF) for archiving the CMIP data and providing access, and the multiple funding agencies who support CMIP5 and CMIP6 and ESGF.
