Thank you for your positive comment.

We will add a conclusion section featuring recommendations for adoption of coupled modelling and will identify research gaps.

We thank the reviewer for their excellent suggestions. Indeed we had overlooked some important pieces of literature, we will read them and add them to the review.

We will follow the reviewers' advice and:

1. rewrite the abstract in a more positive way and be more assertive on the usefulness of coupled modelling as an integrated way of weather forecasting across earth system components

2. we will add more examples of institutions having adopting coupled modelling for weather forecasting, thank you for the useful suggestions

3. we will define the SST acronym

4. thank you for the point on open-source code, it's a very good one

5. we will add a few lines on the different time-scales for data assimilation.

6. we will add the benefit of coupled DA, this is an excellent point we had not considered, as this is not our domain of expertise, thank you.

7. we will also include a comment on the SST or sea-ice extent uncertainty, again we thank the reviewer for bringing this point to our attention.
