Running a global model with 70 vertical levels

Description

Hello,

I'd like to run the global UM vn6.1 to generate LBCs for a case study from December 2009. I usually run this same setup at a resolution of 640x481 and 50 vertical levels. However, the startdump file I have now has the same horizontal resolution but 70 levels. The other difference with 50-level startdumps is that the new one seems to have three extra fields (STASH=21,STASH=212 and STASH=351).

I've tried to run the usual 50-level setup (example job xdgna) changing the obvious parts to 70 levels taking parameters from example job xeria (the only one I found with 70 levels).

The run did not start complaining with the following error message:

*

ERROR!!! in reconfiguration in routine Rcf_Exppx

Error Code:- 2

Error Message:- Cant find STASH item 21 section 0 model 1 in STASHmaster

Error generated from processor 0
*

What would you think is the best way to proceed in this case?

Thanks,

Oscar

Hi Oscar,

I tried a reconfiguration only run with the standard UM7.1 job xebsa. This is 640x481x50. This resulted in the right grid but the start dump included stash 351. To get rid of this you need to go to Scientific sections > Aerosol and select Areo_clim; switch off include biogenic aerosol climatology. Then select Aero ancils and select not used for the biogenic aerosol climatology.

For reference, the stash codes that you refer to are,

  1. 21 = CCRad:lowest convective cloud base layer
  2. 212 = CCRad: CCW passed to radiation
  3. 351 = CLIM Biogenic aerosol MMR

As ever, the more recent start dumps tend to contain new fields.

Regards,

Willie
