Greenland 2019-20 SMB (Snowfall & Melting) Year

(1/7) > >>

gerontocrat:
I am starting this thread so these posts conform to the DMI Greenland Year September to August as in their website http://polarportal.dk/en/greenland/surface-conditions/.

Also, if I ever get to see new GRACE-FO data on overall Greenland Ice Sheet Mass this looks like a good place to put it.

The Greenland 2019 melting Season thread is staying open, as there will be many 2019 reports coming out to the end of the year and beyond.

blumenkraft:
That naming will surely prevent weekly questions about the meaning of SMB. ;)

gerontocrat:
http://polarportal.dk/en/greenland/surface-conditions/ as at 7 September


MELT continues to fall in line with the average,

PRECIPITATION has been higher than average,

so as a result, in this first week of the new DMI Greenland year, SMB gain is above average

Quote from DMI

--- Quote ---The Greenland Ice Sheet evolves throughout the year as weather conditions change. Precipitation increases the mass of the ice sheet, whilst greater warmth leads to melting, which causes it to lose mass. The term surface mass balance is used to describe the isolated gain and loss of mass of the surface of the ice sheet – excluding the mass that is lost when glaciers calve off icebergs and melt as they come into contact with warm seawater.

Gerontocrat,

Thank you for keeping track of this. Please check the units and the numbers on your second graph. It sure seems like a lot ice per square km.

Thanks

It's not that much. A ton is something close to 1 by 1 by 1 meter. A km2 is 1 million m2 . So a layer of 1 km2 and 1 meter thick is a million tons. That makes 7000 tons close to nothing.
