UM version conversion from 4.7 to 4.5.1

Description

Hello

I have a UM vn4.7 basis file which I would like to upload as vn4.5.1. (The person who provided me with the vn4.7 basis file cannot supply a 4.5.1 version.)

The variables in the vn4.7 basis file that are missing from a (sample) vn4.5.1 basis file
are listed below together with their values. Please could you tell me what these 4.7-specific variables do and whether it would matter (scientifically) if I ignore them when I upload the vn4.7 basis file as vn4.5.1 using umui?

MASS_GENPREF='trnb_'

MASS_TEMPLATE='CR_L '

USE_MASS='Y'

CLROPT='CLR '

MACH_NEC='SX6 '

USE_UMMODS='Y','Y',…

UPDATF='$AT_MODS1/gan1f407.mf77 ',…

LEXTRA_STREAMS='N'

COMP_NEC='N'

UMDIR_OPT='N'

USEMBTO='N'

Many thanks,
Kuniko

Hello,

In general we don't think that it should matter that you upload a 4.7 job as a 4.5.1 job. Your sample missing 4.7 variables are mostly UK Met Office specfic variables which are only of use when running on the Met Office system

However you should remember that the 4.5.1. and 4.7 program libraies will have different line numbers and so any 4.7 modsets that you have got with your 4.7.1 basis file will have to be changed for the 4.5 program library numbering.
