The Greenland Ice Sheet loses mass when the sum of surface melt, surface water vapor flux, submarine melt, and discharge of solid ice exceeds the accumulated snowfall and rainfall. Net mass loss has occurred annually since the 1990s (Mouginot et al. 2019; Mankoff et al. 2021). Three independent estimates of the mass balance of the ice sheet over the 2024 mass balance year (1 September 2023 to 31 August 2024) are presented: input–output-derived mass balance of −76±48 Gt, gravity-derived mass balance of −55±35 Gt, and elevation-derived mass balance of −98±63 Gt. These three independent values agree within measurement uncertainties. All three measurements indicate that the Greenland Ice Sheet lost mass; however, the loss was 50%−80% less than the 2002 − 23 annual average.
