Hi Fadzil,

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.

I have jobs to reconfigure this data: xklhe (N216) and xkmoc (N512) at UM8.2. You can take a copy of these.

Chris asked about SST data. We can get SST data from ECMWF and Simon Wilson has a method for converting these into ancillary files, if that helps.

Hi Willie,
Thanks for the data.

We have a few questions regarding the reconfiguration process.

  1. Is it OK for us to use version 8.2 (xkmoc) for reconfiguration if we are running the model later on using version 8.5 with ENDGame?
  2. We would like to use SST from at least one of the ECMWF dumps 20120430_00.grib, is it possible for us or you to convert that to ancillary?
  3. Most of the file are needed as input to MakeBC. What is the easiest way to convert these to UM format? Chris used to use an offline script from Grenville to do this, but that script doesn't work for the new version of grib. Can xkmoc be run with multiple input dumps?
  4. Is there a version of xconv that can read the new grib format?

Hi Fadzil,

1 Yes, the models are backwards compatible.
2 I've created a start dump with SST (20120430_00_sst.grib) and an SST only (20120430_sst.grib) files on ARCHER in /work/n02/n02/wmcginty. Please copy ASAP. I have never reconfigured a start dump plus SST GRIB file but it may well be possible. If you want to go the ancillary route you should contact Simon Wilson.

  1. Normally you would do a global run with the MAKEBC STASH macro switched on. The output fields files are then used in MAKEBC. xkmoc can be run on a list of start dumps: see the attached document.
  2. On ARCHER, ~jwc/bin/xconv1.92 works.

Hi Willie,
I've copied all the dumps files to my work folder.
Thank you for the explanation as well.
