Dear Authors,
I think you adequately replied to the reviewers’ comments. I suggest you submit a fully revised paper which I shall then send again to the two reviewers for their assessment.
Please make clear which changes you have made to the original text and motivate
these in a separate letter.
Sincerely, Hubert Savenije

Dear Authors,

The two reviewers were satisfied with your revision, but reviewer #1 made observations which I recommend you address. I leave it to you to decide how you incorporate these observations, which I copy here below:

The revised manuscript has been considerably improved and the authors clarified most of the points I outlined in my first assessment.

Yet I'd like to stress that thermodynamic entropy and information entropy are not independent. They are well connected in the field of statistical mechanics; in fact one can show that thermodynamic entropy equals Shannon entropy times the Boltzmann constant when relating the Shannon entropy of micro-canonical ensemble with the number of micro states the same represent the energetic macro state of a system (compare for instance Hohnerkamp and Römer, classical theoretical physics). And the fact that the authors claim that entropy shall me maximized makes only sense in the light of the second law of thermodynamics, and not for information entropy itself. The entire discussion relates also to the question where energy is dissipated and entropy is produced, through internal dissipation or through exchange at the boundaries.

Secondly I’d like to stick to the comment that long wave radiation is not an independent variable. In my comment I didn’t mean that the authors shall violate energy conservation, but that a free optimization would imply include long wave radiation as a free variable (as function surface temperature etc.).
