Hi @huazhen, are you looking to follow the first method mentioned in the [linked topic](https://forum.access-hive.org.au/t/ensemble-runs-with-access-cm2/1107/5), which adds a perturbation to the atmosphere’s temperature field?

I’m unsure about the details of the second method mentioned as the instructions may have moved.
