PY - 2019/07/08 Y2 - 2024/03/28 TI - Greenland ice sheet mass balance assessed by PROMICE (1995–2015) JF - GEUS Bulletin JA - GEUS Bulletin VL - 43 IS - SE - RESEARCH ARTICLE | SHORT DO - 10.34194/GEUSB-201943-02-01 UR - https://geusbulletin.org/index.php/geusb/article/view/4276 SP - AB - <p>The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) has measured ice-sheet elevation and thickness via repeat airborne surveys circumscribing the ice sheet at an average elevation of 1708 ± 5 m (Sørensen<em>&nbsp;et al.</em>&nbsp;2018). We refer to this 5415 km survey as the ‘PROMICE perimeter’. Here, we assess ice-sheet mass balance following the input-output approach of Andersen<em>&nbsp;et al</em>. (2015). We estimate ice-sheet output, or the ice discharge across the ice-sheet grounding line, by applying downstream corrections to the ice flux across the PROMICE perimeter. We subtract this ice discharge from ice-sheet input, or the area-integrated, ice sheet surface mass balance, estimated by a regional climate model. While Andersen<em>&nbsp;et al</em>. (2015) assessed ice-sheet mass balance in 2007 and 2011, this updated input-output assessment now estimates the annual sea-level rise contribution from eighteen sub-sectors of the Greenland ice sheet over the 1995–2015 period.</p> ER -
