Ancillary Files

Description

Hi

I've got a bunch of Ancillary files I want to use to run the model with. I believe the way this is supposed to be done is by editing a file to include the ancillary files rather than through the UMUI. Is there any documentation on this? And if so where?

thanks
Simon

Hi Simon,

It is easiest to do this via the UMUI on the ancillary pages. You can set up variable names on the Time Convention and script page e.g. ANCIL_DIR1 and then on the ancillary page (e.g. ozone )specify the directory and file name of the ancillary file. This is quite readable.

For an example of the method you mention, see job xgxrc (UKV 7.8). Here the ancillary set up is specified in two files under Ancillary > In files > Ancillary version files. The first file (Ancil filenames version) specifies a list of variables which are the filenames of the ancillary files. The second file (Ancil versions file) specifies a list of variables which are the directory names of where the ancillary files are located. Then each ancillary page (e.g. ozone) has the variables names for the directory and file. This method is sometimes used at the Met Office because they have a large ancillary file system to maintain over many models and versions. We at CMS replicate a part of this system in $UMDIR/ancil.

Regards

Willie
