Hello, I’m working to get my suites running on monsoon3 (previously running on monsoon2). There are a few directories that don’t exist on monsoon3 (but did on ..2). I have listed some of them below. Are these located elsewhere? Or can they be moved/reinstated on monsoon3?

Thanks, Ross

/projects/ukca-admin/inputs/ancil/n96e/cmip6/ocean/MEDUSA (and AeroChemEms, and sstice)

Hi Ross,

Try:

_/projects/ukesm/jeremy.walton.mon/ancil/MEDUSA/_ for the first.

Replace /projects/ancils/cmip6 with _/common/share/monsoon\_ancils\_cmip6/_ for all CMIP6 ancils

and /common/share/monsoon\_ancils/atmos/n96e/ukca\_emiss/biogenic/v1

Excellent thanks Mohit.

I was also using Reynolds SSTs which I found in their usual monsoon2 location (_/projects/ukca-admin/inputs/ancil/gregorian/n96e/reynolds/v2.1_). I’ll assume that’s fine to use unless you say otherwise.

Thanks, Ross
