If you follow the link to the DMI website, you’ll see that it specifically states: “Satellite observations over the last decade show that the ice sheet is not in balance. The calving loss is greater than the gain from surface mass balance, and Greenland is LOSING MASS at about 200 Gt/yr.” (my caps)

In quantifying the association between Greenland coastal temperatures and Greenland Ice Sheet (GrIS) mass‐balance changes, we show a stronger link of temperatures with total mass balance rather than surface mass Balancing act. Comparing the total snowfall and surface melt against each other gives you the “surface mass balance”. At the Danish Meteorological Institute (DMI), we use output from a numerical weather forecasting model combined with data from observation stations on Greenland to estimate the surface mass balance for the whole ice sheet for every single day. Modeled ice thickness and volume The plots show maps with sea ice thickness, and seasonal cycles of the calculated total arctic sea ice volume. The mean sea ice volume and standard deviation for the period 2004-2013 are shown with gray.

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 Imaginary Greenland Meltdown Is Not Having Any Effect Marine-terminating glaciers are the outlets via which the Greenland ice sheet discharges ice mass to the ocean. When in balance, the rate of iceberg calving (by area) is equalized by the seaward flow of the ice (see the essay on Greenland Ice Sheet Surface Velocity: New Data Sets, 2015 Arctic Report Card for further information on the velocity of these glaciers).

Greenland’s surface has gained 530 billion tons of ice since last summer, and is tracking well above normal. Greenland Ice Sheet Surface Mass Budget: DMI The maps below show the gains (blue shading) and losses (red) in ice mass by August for 2017 (left) and 2018 (right). The eastern part of Greenland has had above average SMB in both seasons while 2019-08-11 · Warm air over Greenland began to emerge around July 29 which (8/18 update: DID NOT) set records at the Summit Station.⁵ By the time temperatures cooled down around August 4th, about 90% of the Greenland ice sheet surface observed melting at least once between the 29th and the 3rd.⁵ July 31st was the most extensive melt day with over 60% of the ice sheet surface seeing melting.⁵ The surface melt extent on July 31 was estimated to be about 984,000 square kilometers (Figure 4).⁶ For comparing recent changes in Greenland tempera-tures with GrIS mass balance, surface mass balance (snow accumulation minus surface meltwater runoff) and solid-ice discharge variations, we use the recently-published dataset of Mouginot et al.
Modeled ice thickness and volume The plots show maps with sea ice thickness, and seasonal cycles of the calculated total arctic sea ice volume. The mean sea ice volume and standard deviation for the period 2004-2013 are shown with gray. The figures are based on calculations using DMI's operational ocean and sea ice model HYCOM-CICE.
A mass balance of –234 ± 20 Gt a –1 (April 2002 to February 2012) was derived from Gravity Recovery and Climate Experiment (GRACE) data ( Reference 1 INTRODUCTION.

Arctic ice continues to rebound to 2004-2013 levels. https://www.dmi.dk/en/groenland/maalinger/greenland-ice-sheet-surface-mass-budget/ 2019 MELT SEASON - 2018-2019 SMB SEASON As at 12 Jan 2019 Some dry days and wet days so far this year. And for the next 5 to 10 days it looks like, - no melt, - below average precipitation, - SMB balance year to date a bit more below average. The reason I’m pointing this is out is that the largest loss of ice in Greenland this year was 11 billion tons.
2018-19 and 2019-20: DMI estimates that the surface of the ice sheet gained 169bn tonnes during 2018-19.

Greenland Ice Sheet Surface Mass Budget: DMI. Greenland’s surface has gained 470 billion tons of ice since August, which is more than 100 billion tons above average for the date. Meanwhile, government funded experts continue to lie about the state of the Arctic in real time.
To clarify again, the mass balance calculation accounts for: 1) Snowfall. 2) Ice melt Daily (upper chart) and cumulative (lower) surface mass budget of the Greenland ice sheet, in billion tonnes per day, and billion tonnes, respectively. Blue lines show 2020-21 SMB year.
Nov 30, 2012 Until this is achieved, observations of ice-sheet mass imbalance remain allow for a combined Greenland and Antarctic ice-sheet mass imbalance of The error budget was calculated from uncertainties in the corrected
