n1850.ne30_tn14.hybrid_fatessp.20241111

[mvertens]

Purpose:
Duplicate of n1850.ne30_tn14.hybrid_fatessp.20241031 but with an updated twostream scheme for FATES.
The only difference with n1850.ne30_tn14.hybrid_fatessp.20241031 is a change to user_nl_clm (see below).
The goal is to run 20 years.

---

Description:

• use of FATES-SP and cold start.

• NOTE: a memory leak is present in the run and hits agains the node limit when running past 11 years.
  See memory leak in n1850 case NorESM#550

• comparison to the previous simulation: https://ns2345k.web.sigma2.no/datalake/diagnostics/ADF/plots/n1850.ne30_tn14.hybrid_fatessp.20241111_1_7_vs_n1850.ne30_tn14.hybrid_fatessp.202401031_1_7/website/index.html
• comparison to NorESM2-MM piControl (almost done!): https://ns2345k.web.sigma2.no/datalake/diagnostics/ADF/plots/n1850.ne30_tn14.hybrid_fatessp.20241111_1_7_vs_N1850frc2_f09_tn14_20191001_1200_1206/website/index.html
• Unfortunately there is a bug in ADF which makes it crash when I try to compare to observations. I haven't had the time to fix it yet.

Extra details:

[adagj]

Hi, Is this simulation running? Do we meet on Thursday or is that too early? @kjetilaas

[kjetilaas]

Yes, this is running, but I didn't manage to start it before Monday so it will not be ready before tomorrow morning. It has completed about 11 years, so it will probably finish late Thursday or Friday.

If it is only this simulation, we might skip the meeting tomorrow. But if we think it would be useful to meet anyway, we could make some plot from the first 10 years or so.

What do you think? @rosiealice @mvertens @adagj

[adagj]

Let's meet tomorrow :-)
Please add relevant figures here: https://docs.google.com/presentation/d/1TrlG5HttOVeCu8PXJhe4jK4kYWivKnIOrT65U-XzWMc/edit?usp=sharing

[kjetilaas]

@adagj, now the rest of the simulation is finished and archived (same folder).

@mvertens, I have uploaded the case information with CaptureCase. I hope I did it right?
