<!--!introduction!--> As the climate warms, the grounded ice sheet and floating ice shelves surrounding Antarctica are losing mass at an increasing rate and injecting the resulting meltwater into the Southern Ocean. However almost all existing coupled climate models lack the ice physics required to represent the dominant sources of Antarctic melt. Previous studies have inserted additional Antarctic meltwater into models, demonstrating a wide array of impacts on the climate system. However, these previous studies have used both different forcing and different models, and have reached differing conclusions on the influence of meltwater-climate feedbacks. The Southern Ocean Freshwater release model experiments InitiAtive (SOFIA) defines a consistent series of experiments, including idealized meltwater experiments, historical experiments, and future scenarios, all with plausible meltwater inputs. Here we present the SOFIA experimental design, and quantify the response and uncertainty to idealized 0.1 Sv ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
