Data consists of surface mass balance (SMB) derived using stake height measurements of 90 stakes installed and successfully reoccupied over Blåskimen Island ice rise in western Dronning Maud Land. It uses firn density measured using 3 m deep firn cores at 11 sites over the ice rise to account for the spatial variation in density. The SMB represents a one year period between 2013 and 2014. The data are provided in MATLAB (.mat) file format. <br> IRD_smb_stake.mat includes – <br> • ‘x’ and ‘y’ arrays with coordinates in a polar stereographic projection parallel to 71° S (EPSG 3031)<br> •‘dh’ array with measured stake height difference over the given period<br> •‘rho’ shows the density used in the estimate<br> •‘smb’ the surface mass balance in kg m-2<br> See the following manuscript for further details: Goel, V., Brown, J., and Matsuoka, K.: Glaciological settings and recent mass balance of Blåskimen Island in Dronning Maud Land, Antarctica, The Cryosphere Discuss., https://doi.org/10.5194/tc-2017-61, in review, 2017.
