WebSep 14, 2024 · 1. Introduction. It has been pointed out by several authors that meltwater retention has a significant effect on the surface mass balance of the Greenland ice sheet (e.g. Reference Pfeffer, Illangasekare and Meier Pfeffer and others, 1990, Reference Pfeffer, Meier and Illangasekare 1991; Reference Reeh Reeh, 1991; Reference … WebTotal Ice Mass Balance. GRACE satellite data can be used to estimate monthly changes in the total mass of the Greenland ice sheet, as done in the past (e.g., Tedesco et al., 2024). However, the NASA GRACE mission, which started in 2002, ended in October 2024. Hence, there are no data available on the total mass balance for the 2024/18 season.
