vn10.9 UKCA STASH issues

Description (last modified by willie)

Hi,

Monsoon

Rose suite: u-az303 running UKCA vn10.9

Output after 1 month run: moose:/crum/u-az303/

I am trying to output u,v and T on all model levels and every 6 hours so I can use the output file to nudge a different model run.

I am confused about how domains work.

In STASH, I changed the dom_name of these 3 variables in stream UPC to be 'DALLRH'. After the run, I seems to be getting all horizontal grid points (nx=192, ny=145) but only 17 vertical levels.

On the other hand,

V COMPNT OF WIND AFTER TIMESTEP, output to UPG 
dom_name=DALLRH 
nx=192, ny=145 and nz=85

but

U COMPNT OF WIND AFTER TIMESTEP, output to UPG 
dom_name=DALLRH 
nx=192, ny=144 (!) and nz=85

I am using xconv to look at the pp files.

Cheers,
Alison

Hi Alison,

Are you running this on Monsoon?

If you change the STASH then you need to run the STASH TidyStashTransform macro afterwards to re index the table.

I notice your suite has a large number of errors - these are the little red triangles in the left window. This might be because I'm looking on the wrong computer. But it is not a good idea to run the model with errors.

Regards
Willie

Hi,

Yes this in on monsoon. I had forgotten to STASH TidyStashTransform?. Thanks!

The large number of errors is because I have added a number of stash items and they go away when I open the suite with -M path/to/correct/stashfile.

Thanks,
Alison

Hi,

The STASH TidyStashTransform? has made the sizes of u and v consistent. I still have a problem of them being on 17 levels rather than 85.

On Monsoon, to edit the suite, I use

rose edit -M /home/d01/almin/vn10.9_cl2_photolysis/rose-meta

Cheers,
Alison

Stream UPC doesn't output the same U,V,T as does UPG; it outputting

TEMPERATURE on P LEV/UV GRID
V COMPONENT of WIND on P LEV/UV GRID etc

are those what you want?
