Hi Zhen,

Which computer do you want the data copied to?

Hi Willie,

Sorry to mention about this, I want to copy the data to archer. Thanks.

  • Component changed from UM Model to Data
  • Platform set to ARCHER
  • UM Version set to 10.7

Hi Zhen,

Your data is now ready on ARCHER in /work/n02/n02/wmcginty/data_xfer. Please copy it to your own work space as soon as possible.

This is an ERA-I GRIB file containing basic fields only. There are no UM files at the Met Office prior to 2006.

Hi Willie,

Thanks. I have copied the file. Please feel free to delete the data.
May I ask that can this grib file be used as start dump for UM10.7 directly? Or I need do some pre-processing? Thanks.

  • Component changed from Data to UM Model
  • Platform ARCHER deleted
  • UM Version 10.7 deleted

I see there is one option called input_dump_type in the interface of Rose. I guess it works without any changes.

Cheers,
zhen

Hi Willie,

I change the input_dump_type to GRIB to use the grib file you send to as start dump on Archer. But the model failed at reconfiguration with the error:
? Error code: 100
? Error from routine: UKMO_DECODE
? Error message: Attempting to read GRIB data, but GRIB_API ifdef not present
? in build. Please note the GRIB API is currently the only method
? for decoding GRIB
? Error from processor: 12
? Error number: 2
Do you know how to solve this problem?

Thanks.

Hi Zhen,

You need to add in one of my branches and rebuild your code. See the instructions at
ticket:2739#comment:18.

Hi Willie,

Thanks for your replies.
As my UM version is 10.7 and your branch is UM 11.1, I am not sure whether theses branches will contradict with each other. Thanks.

Best,
zhen

Hi Willie,

The fcm_make_um failed after I add your branch with the error:

Do you get any idea to solve the problem? Thanks.

Hi Zhen,

You can't include an 11.1 branch in a 10.7 suite. You will need a branch at vn10.7 with the equivalent changes in.

Regards,
Ros.

Hi Ros,

If that is the case, do you know where I can find a corresponding branch at vn10.7. I am not sure what changes made by Willie so that the UM can read grib as start dump. Thanks.

Hi Zhen,

Could you upgrade to 11.1 - e.g. u-ba767? This would be the quickest way forward.

At UM11.2, the Reconfiguration was upgraded to use EcCodes? to handle GRIB data, so it is then part of the UM trunk.

Hi Willie,

Thanks for your replies.
It seems to me I find the start dump on Archer under /work/y07/y07/umshared/hadgem3/initial/atmos/N96L85/ab357a.da19810901_00
I am doing a short term test. Hope this UM start dump works.

Cheers,
zhen
