Greenland 2019 Melt Season

2019 MELT SEASON - 2018-2019 SMB SEASON As at 12 Jan 2019

Some dry days and wet days so far this year.

And for the next 5 to 10 days it looks like,
- no melt,
- below average precipitation,
- SMB balance year to date a bit more below average.

SMB = Surface Mass Balance, which excludes mass loss from calving that on average is greater than SMB gain in the year. i.e. usually Greenland loses mass every year.

GRACE follow-on data - where are you?

2019 MELT SEASON - 2018-2019 SMB SEASON As at 19 Jan 2019

Some dry days and wet days so far this year.

And for the next 5 to 10 days it looks like,
- no melt,
- Some dryish days and some wettish days,
- SMB balance year to date stays below average.

In other words - no change

I haven't read the whole paper yet, buy as the study uses GRACE data up to 2016, I would guess the only news is the locality of mass loss. If the Southwest is producing more melt, some other area of the ice sheet is producing less, given that GRACE has measured the total mass of the ice sheet with reasonable accuracy.
The big news will come once the new GRACE data becomes operational. Then we will know if ice mass loss has slowed or even stopped in 2017-18, as indicated by a better surface mass balance and by the seeming slowdown in Jakobshavn calving.

2019 MELT SEASON - 2018-2019 SMB SEASON As at 19 Jan 2019

Some dry days and wet days so far this year.

And for the rest of he month it looks like,
- no melt,
- Some dryish days and some wettish days but overall below average,
- SMB balance year to date further below average.

In other words - not a lot of change
