Implementing Irrigation in 2D simulations of JULES

[mtodt]

Created copy of suite u-bh031. Set directories and names of log files manually in suite.rc.

[mtodt]

Directory of ancillary files has changed from /group_workspaces/jasmin2/ncas_generic/users/pmcguire/jules_ancil/ to /gws/nopw/j04/ncas_generic/users/pmcguire/jules_ancil/.

Markus:
You had found references to Nicola Gedney's, Toby Marthews's, et al's TOPMODEL ancillary in a couple of diferent suites. This ancillary was needed as you determined to run irrigation in 2D. Pier Luigi told me that the GL7 had the TOPMODEL enabled in it. So I looked at the GL7 suite from Carolina Duran Rojas and Andy Wiltshire et al (u-bb316).
And the TOPMODEL ancillary is pointed to in there:
$ANCIL_DIREC/qrparm.hydtop.nc
where (on JASMIN):
ANCIL_DIREC= "/group_workspaces/jasmin2/jules/data/Ancillary/n96e/GL7/fixed/"
ANCIL_TIME_DIREC= "/group_workspaces/jasmin2/jules/data/Ancillary/n96e/GL7/time_varying/"

Hi Patrick

Thanks a lot for looking up those TOPMODEL parameters! But there are only n96-resolution files, and I assume we can't just interpolate a topography index to 0.5x0.5 degrees. So, I think we need a file for 0.5x0.5 degrees that is derived from the original dataset. I am in contact with Nicola Gedney at the moment and she might be able to help with that.

Cheers

Hi Markus
Maybe the authors of the GL7 suite know about the availability of the TOPMODEL ancillary files for the GL7 suite for other resolutions?
The authors are Carolina Duran Rojas and Andy Wiltshire.
I tried to find these files on the MONSOON supercomputer, but I haven't been successful.

That might be the best way going forward, although I sent an email to Andy Wiltshire last week when Nicola was out of office and he said he couldn't help.
Nicola shared her TOPMODEL file with me just now, the one she uses in suite u-bi728 (seems to be based on vn4.7). It's on JASMIN at /home/users/mtodt/Data/TopographyIndex/CRU-NCEP-0p5-timean-tisd-fexp-marthews-halfdeg-wfdei-land.nc. Do you want to copy it to one of the group working spaces?

Cheers

Hi Markus:
Do you have any info to add to this ticket?
Should it be left open?

Oh boy, I completely forgot about this task ticket! I suppose I can outline everything I've done over the last ~18 months. That way I can share it with other people, at least, instead of just having my own notes. So let's keep it open and I'll update it soon.

Cheers
