Convert UM output

[a.elvidge]

Hi,

I have UM output in multiple files as follows
xfxkda_pa0000, xfxkda_pa0100, xfxkda_pa0200 etc

I would like to input a selection of the output fields from these files into NDdiag. I will need to use ff2pp first. So, I think I need to extract and ccombine the output for the relevant fields from my output files into one ff file to input into ff2pp. Can I do this in xconv? If so, how? If not, is there another way of preparing the relevant fields to be compatible with NDdiag.

Thanks, Andy

Hi Andy,

I would convert the files individually using ff2pp and then use pp_merge to combine them in time step order for input to NDdiag. See http://cms.ncas.ac.uk/index.php/tools-and-utilities/um-tools/1363.

Hi Willie,

Thanks. But, my output files include additional fields (not required by NDdiag). Is there any way I can leave these out? Would NDdiag complain if they were left in? In any case, since I will need to scp the data between computers, it would be beneficial if I could leave them out somehow.

Thanks, Andy

Hi Andy,

You could try filtering the PP files using pp_getfields - it's on the same web page.
