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. For comparison, the mean curve from the period 1981-2010 is shown (dark grey). 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.

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.

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. 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.

The calving loss is greater than the gain from surface mass balance, and Greenland is losing mass at about 200 Gt/yr.

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.

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.
