Hi Alison,

It's failing with the error above at the cycle 19881101T0000Z after running for 421 time steps (just over five days). The URL suggests setting the UM print status to "Extra diagnostic messages" in um → Run time controls → Atmosphere only and repeating the run from this cycle. This will provide further information about the problem.

Also in your suite, the UM meta data (under um) is wrong - it set to um-atmos/HEAD. It should be um-atmos/vn10.9.

Regards,
Willie

Hello,

I have changed the UM meta data and re run the model with Extra diagnostic messages.

Many thanks,
Alison
