Hi,

I am getting this fail when I try to run a job with a new branch merged into my own:  
? Error from routine: UKCA\_MAKE\_TR\_MAP  
? Error message: Failed to set tr\_lookup

I have merged in fcm merge fcm:um.x\_br/pkg/lukeabraham/vn11.1\_CCMI to my branch vn11.1\_vn11.1\_CCMI\_test and have made the relevant changes to u-dd765.

Thanks,  
Hannah

Hi Hannah,

This is coming from `ukca_all_tracers_copy_mod.F90` and occurs when an extra advected tracer(s) is expected but isn’t found. I would suggest looking through what species you are expecting and if they are all specified correctly. For instance, there will be an O3S tracer in the CCMI branch that you may not be expecting etc. Take a look through any other output higher up the output files - you might be best to look at the ones in the `pe_output/` directory - to see what the other messages are saying about UKCA up to this point.

Best wishes,  
Luke

Hi Luke,

Thank you! It was a missing STASHMASTER = STASHmaster so the new meta data was being missed. Apologies for not spotting that.

Thanks,  
Hannah

Hi Hannah,

Ah - of course. The way that a new STASHmaster file needs to be included is unfortunaltely error prone with how Rose works.

Best wishes,  
Luke
