@matthew.chamberlain The ESM1.6 “team” has discussed this.  
It turns out there is [a reason](https://forum.access-hive.org.au/t/access-esm1-6-development/3114/280) why these diagnostics are not enabled in the current setup: we had to turn off the collation and these diagnostics don’t work without it, according to @spencerwong who worked on this.

We have a plan to review the ESM1.6 outputs in the coming weeks so we’ll consider this as well and see whether we can get this to work.
