www.dmi.dk Side 4 af 19 Abstract Recent observations have indicated rapidly increasing mass loss from the Greenland Ice Sheet. To explore the interactions and feedbacks of the ice sheets in the climate system, it is important to 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. 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.

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. This year, thanks partly to Nicole’s snow and partly to the relatively low amounts of melt in the summer, we estimate the total mass budget to be close to zero and possibly even positive.

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.

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].

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. 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) Top: The total daily contribution to the surface mass balance from the entire ice sheet (blue line, Gt/day).
