Er det noen som har lurt på hvorfor DMI ikke oppdaterte grafene sine for Grønlandsmassivet (Surface Mass Balance; SMB) på flere dager (i dag er det 21. oktober 2023). Nå vet vi svaret: Veksten i SMB har sprengt standardformatet for chartet deres! For nå ser vi tilvekstgrafen fortsette ut av chartet!

HISTORIC SNOW/ICE GAINS ON GREENLAND
The Danish Meteorological Institute's daily Surface Mass Balance (SMB) dataset
failed to update late last week. I think I now know why. The DMI was probably
seeking to validate this monstrous gain before going public with it:
They were probably working out if they needed a bigger
chart, and they likely did, but what a PR nightmare that would have been.
On Wednesday, October 18, a recording-smashing 12+ gigaton gain was posted by
the ice sheet, the highest daily total ever recorded in DMI record books dating
back to 1981.
Another 9Gts was picked up Thursday.
Then 8Gts Friday.
These are astonishing gains of early-season snow, which practically buried the
southeast section of the island; gains that have pushed the season's
accumulated SMB well-above the 1981-2010 mean (bottom panel below) to rival
last year's record readings.
Det skal bli interessant å følge denne utviklingen videre.
Men denne voldsomme veksten over noen få dager vil neppe kunne vedvare så
lenge, man må ut fra lange historiske data anta at en slik ekstrem anomali vil
roe seg litt ved nye vær- og nedbørforhold, som i tidligere år. Uansett vil det
bli spennende om Grønlandsmassivet også det neste året fortsetter den stigende
trenden siden 2012.
