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. The focus of PROMICE is maintaining a network of automated climate stations in the ice sheet melt area to observe surface mass budget. Cumulative surface mass budget of the Greenland ice sheet for 2019-20 (blue line), the record low SMB year of 2011-12 (red), and the 1981-2010 average (grey). Credit: DMI Polar Portal.

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. The period 2003-2011 has seen ice sheet losses on Greenland averaging 234bn tonnes each year. The neutral mass change in the last two years does not – and cannot – begin to compensate for these losses.

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.

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.

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. 2017-08-13 · Once the AMO enters its 30-yr cool cycle from around 2019, global temps start cooling from the 30-yr PDO cool cycle (which already started), additional global cooling occurs from the coming La Niña cycle, and even more cooling occurs from the approaching 50~100-year Grand Solar Minimum event, I think it’s highly likely 2017 could mark the turning point of gradual Arctic Sea Ice and net Since at least 2002, the total mass budget has been substantially negative, with the Greenland ice sheet losing around 200-300bn tonnes of ice each year.

Based on these simulations, an overall assessment of how the surface […] 1 Introduction. 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].The contribution of these two processes to total ice sheet loss was approximately equal during the first decade of the 21st 2016-06-26 Daily (upper chart) and cumulative (lower) surface mass budget of the Greenland ice sheet, in billion tonnes per day, and billion tonnes, respectively.
