This year our analysis suggests Greenland discharged around 498bn tonnes of ice. Factoring in these additional processes, we can calculate the total mass budget for the ice sheet for the year. For 2018-19, we estimate the ice sheet has seen a total net ice loss of around 329bn tonnes.

Previous uses of the DMI graph includes 'Greenland Ice Growth Ahead Of Last Year’s Record Pace' (Oct 2017) which seems oddly careful to specify that DMI does show surface mass balance given that it goes on to talk of 'criminals in the press and academia'; 'Record Greenland Ice Growth Continues' (Sep 2017); 'Scientists Discover That Their strongly correlated with Greenland Blocking than with North Atlantic Oscilla-tion changes. In quantifying the association between Greenland coastal tem-peratures and Greenland Ice Sheet (GrIS) mass-balance changes, we show a stronger link of temperatures with total mass balance rather than surface mass balance. How the Greenland ice sheet fared in 2018 "surface mass budget" (SMB) of the ice sheet. average and red shows more ice loss than average.

1 INTRODUCTION. Recent research highlights increased mass loss from the Greenland Ice Sheet (GrIS) (Shepherd et al., 2020; Hanna et al., 2013a; Hanna et al., 2020; Bamber et al., 2018), and the ice sheet's response to anthropogenic global warming includes a non‐linear effect of rising air temperatures on melt and runoff (Trusel et al., 2018).

Det gælder særligt for Færøerne og den jyske Vestkyst. The Greenland ice sheet (GrIS) is losing mass as a result of both increased surface melting and runoff and increased ice discharge from marine‐terminating outlet glaciers [Rignot et al., 2008, 2011; Sasgen et al., 2012; van den Broeke et al., 2009]. I think Greenland Mass Ice Budget was removed because they were showing record gains on Greenland ice in 2016, 2017 and 2018.

The launch in 2013 of the website polarportal.dk (polarportal.org in English, a joint production of DMI, GEUS and DTU-Space) now allows anyone to check the current “health” of the Greenland ice sheet, including glacier front positions for selected outlet glaciers based on satellite image and an estimate based of total mass balance using a product developed from GRACE satellite gravity Daily (upper chart) and cumulative (lower) surface mass budget of the Greenland ice sheet, in billion tonnes per day, and billion tonnes, respectively [DMI Polar Portal].

The mass loss has been quantified by three independent techniques using changes in ice volume (6, 7), time-variable gravity , and input versus output fluxes or mass budget method (1, 2, 4, 9 ⇓ –11), for the time period 1992–2016 or 2002–2016. The mass budget method is the only one that provides information about the physical processes controlling the mass loss, i.e., the partitioning between surface mass balance (SMB) processes (accumulation minus runoff and other forms of ablation
