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. The Danish Meteorological Institute (DMI) also performs daily simulations of how much ice or water the Ice Sheet loses or accumulates. Based on these simulations, an overall assessment of how the surface […]

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.

to the uncertainty in projections of ice-sheet melting and other impacts of global land use in Denmark over the last four decades is 14%, and for Greenland there is elevated CO2, from reviewed literature (90 references) on global C budget (Tate Climate Centre Report 06-02, 17 pp., DMI, (www.dmi.dk/dmi/dkc06-02).

Even back in 2015, there was this record of gaining ice. At DMI, we use a weather forecasting model to calculate how much Greenland ice is gained and lost every day. Totalled over the course of a year, from 1 September to 31 August, this gives us the 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 2018-19 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. Credit: DMI Polar Portal.

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.

Journalists like to put intense focus on a single day or week’s worth of melting in Greenland, yet disregard large mass gains in surface mass balance that occur outside of “melt season.”. Figure 5. 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.

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 mean. For this year, the DMI scientists calculated a total SMB of 517bn tonnes, which is almost 150bn tonnes above the average for 1981-2010, ranking just behind the 2016-17 season as sixth highest on record.
