[Liwg-core] Fwd: simulations

Hi Leo,

If you have a spare moment, can you clone 129 from Cécile, and start a branched off simulation with shifted ramp + bug fix in radiation penetration + lower ice albedo?

I would run it for ~10 years, and then analyse the output, before deciding whether or not to extend it.

Thanks!

Jan

Hi Jan

If you can, it'd be great if you could perform the tests yourself, but make sure you get the latest setup
from Cécile.

Hi J-F,

Thanks. Just to avoid confusion: should we perform these tests ourselves, or will there be a new ‘common’ control simulation that includes our latest changes?

All the best,

Jan

Hi Leo

Thanks for the quick check. Yes, there is still time to look at albedo changes, but it would be best to
start from 129 if you can.

Cheers,

Jean-François

Hi Jean-François,

(1) I quickly checked the melt and SMB values for run 129, there is no change from run 126. SMB sits at 531 Gt/yr.

(2) If that's still possible, that would be great.

Best,
Leo

Hi LIWG

a couple of thoughts after the meeting

1) can you look at 129 to see what the SMB is in this case?  Do you
need to have a few more years?
2) it might be worth to do the albedo tuning in 129 since, according to
Dave, the Arctic vegetation will not change (and so the T response we are seeing now should be staying).

Hope this helps.  Cheers,

Jean-François
