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?

Arctic background / Arctic Background Data Library

« on: February 22, 2018, 09:38:06 PM »

With considerable trepidation, I start a new topic.

A lot of stuff we post is of long-term interest that should be kept, but gets lost into history as the seasons change and so do the threads, I don't know about you, but my PC is cluttered up and old, I am losing stuff already. So I suggest we need a place to put it, or at least the links. The ASI graphs are already safely locked away but accessible.

I found a site today that many of you probably know
- http://sites.uci.edu/zlabe/arctic-temperatures/

It is the sort of data that is of long-term interest. An example is the 925hPa temperature history from 1958 to 2017, I had never come across before, which no doubt Zachary will keep going (automated already?)

If you use it, please note the title "Arctic Background Data Library" - i.e. for data, not opinion. no "near human extinction" diatribes).

A brief description of the data and the link to it (external or internal within ASIF) might be all that is necessary. I will be posting a few tomorrow.
