9-PFT Vegetation Fraction Ancillary

Reported by: mtodt Owned by: pmcguire
Component: UM Model Keywords: 9 PFTs ancillary start dump pre-industrial
Cc: Platform: ARCHER
UM Version: 11.5



I'm trying to run a pre-industrial simulation on ARCHER with 9 Plant Functional Types (PFTs) instead of 5 PFTs. However, I can't find an ancillary file of vegetation fraction for 9 PFTs in the directory that I use in my simulations with 5 PFTs. Are there any 9-PFT ancillary files on ARCHER, and if so, can you point me to the directory? Also, are there start dumps for pre-industrial simulation on ARCHER that I could use? Thanks a lot in advance!

Is this still a problem?


comment:2 Changed 9 months ago by mtodt

Yes, it is. There might be a solution for the vegetation ancillaries, but I don't have a suitable start dumps yet.

Additionally, I am also looking for pre-industrial HadISST forcing data. I had a look on ARCHER but couldn't find any. Is that available from another source? Thanks a lot!

Ancillary files are never easy to find - try searching for a suitable suite in rosie go - I searched for hadISST and the first suite to appear is u-bs561 (GA7.1 amip-piForcing with HadISST1 SSTs (still AMIP sea-ice)) - maybe you can have a more thorough search & contact a suite owner.

Hi Markus
I emailed you privately about this, but here is an edited and expanded version of a response for you and for the CMS Helpdesk.

Can you apply for a JASMIN-specific MASS account and access to the 'Met Office MASS client machine at CEDA', and follow the rest of these instructions?:
SInce the MASS data is available on JASMIN, then users can access the data directly.
After getting the permissions above, you can get start dumps for yourself.

I will transfer 1-2 start dumps for you and for us, but after that you could do it directly from JASMIN more easily than asking me to do it.
The first start dump you requested is on ARCHER at:


It was on the external Monsoon, accessible like this:

@xcslc0:~> moo get -v :crum/u-aq281/ada.file/aq281a.da21271201_00 aq281a.da21271201_00

@xcslc0:~> scp -p aq281a.da21271201_00 pmcguire@…:/work/n02/n02/pmcguire/start_dumps/.

Do you also need another start dump? Do you need any Vegetation ancillary files?

Hi Grenville, Patrick

Thanks a lot for your help! I'll register for a JASMIN-specific MASS account (see private email) and have a further look into this.

Hi Markus:
Any news about this ticket?

Hi Patrick(, Grenville)

I think my suite is running successfully, or at least not failing because of ancillary files. So I think this ticket can be closed.
