• Description:
  Greenland ice sheet total mass change for 1 September 2020 to 31 August 2021 was -85 ± 16 Gt, 179 Gt less than the 2002-21 average of -264 ± 12 Gt yr–1. High variability characterized 2021 surface melting with a two-week long August period of increased melt and bare ice exposure contrasting with low June and July melt conditions. An overall average melt obscured strongly contrasting spatial and temporal melt patterns. On 14 August 2021, Greenland experienced the latest date of an extreme melt event (>50% area) within the 43-year satellite record, including the first reported rainfall at Summit Station, Greenland.
