Two thirds of the Greenland ice sheet's current mass loss stems from its surface mass budget with iceberg production accounting for the remaining mass loss. Greenland Ice Sheet SMB through 2017-18 (top) and 2018-19 (bottom) shown as blue lines. Grey lines show the 1981-2010 average and red shows the record low of 2011-12. Credit: DMI Polar Portal. When you look at the blue lines on the above graphs, it is quite evident that the Greenland Ice Sheet surface mass budget is far, far higher than the Greenland is used as a bellwether for ice in general and sea levels as well. In the 2016/17 time periods the ice has grown well over the average growth rate.

The Guardian report cited by Steve/Tony does in actual fact date from May 5th 2015. For an up 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 Feb 14, 2010 Fluctuations in the Greenland ice sheet (GrIS) surface mass balance (DMI)] observations from inside and outside the GrIS were used to Aug 26, 2014 Large uncertainties exist concerning the impact of Greenland ice sheet melting on the Atlantic meridional overturning to compute a proper budget of the salinity changes in the North Atlantic DMI, Copenhagen, Denma Nov 23, 2016 of the ice sheets.

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.
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.
Strong deceleration in total mass balance (TMB) Next we consider both the SMB and the Discharge together. Here we see that Greenland’s total mass balance TMB (red curve) is negative, meaning a net ice loss in total, but has been decelerating since 2012.
2019-03-11 · Greenland Ice Sheet Surface Mass Balance 2017/18. http://www.dmi.dk/en/groenland/maalinger/greenland-ice-sheet-surface-mass-budget/# As I reported last September, Greenland’s ice sheet mass balance had grown at close to record levels for the second year running. 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.
DMI’s filer med tidevand er nu opdaterede og dækker helt frem til 2022. Traditionen tro er der kommet endnu flere stationer til, og de gamle analyser er genberegnede med nye målinger. 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. Even back in 2015, there was this record of gaining ice. Danish Meteorological Institute (DMI) has for the second year shown record ice growth across the Greenland Ice Sheet, but NASA shows a 281 gigaton loss, oops
Greenland; glaciology; sea level; climate change; glaciers; In the last several decades, the Greenland Ice Sheet (GIS) has lost mass to the ocean (1 ⇓ ⇓ ⇓ –5).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
Bottom: The accumulated surface mass balance from September 1st to now (blue line, Gt) and the season 2011-12 (red) which had very high summer melt in Greenland.

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. The grey lines show the 1981-2010 average, and the red line in lower chart shows the record low SMB year of 2011-12 [DMI Polar Portal]. However, it is likely that the relatively high end of season SMB will mean a zero or close-to-zero total mass budget this year, as last year.
Two thirds of the Greenland ice sheet's current mass loss stems from its surface mass budget with iceberg production accounting for the remaining mass loss.

Log In. or In 2018, Greenland’s total surface mass budget (SMB) is almost 150bn tonnes above the average for 1981-2010, ranking as sixth highest on record. 12 July 2018 THE GLOBAL WARMING POLICY FORUM — The Danish Meteorological Institute (DMI) also performs daily simulations of how much ice or water the Ice Sheet loses or accumulates.
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]. 2018-19 and 2019-20: DMI estimates that the surface of the ice sheet gained 169bn tonnes during 2018-19.
At DMI, we use a weather forecasting model to calculate how much Greenland ice is gained and lost every day.
