Dear Authors,

Please upload your revised manuscript and responses to the reviewer comments according to the instructions you will be provided by e-mail. In addition to the responses you have already posted in the discussion forum, I would ask that you explicitly address the following comment by Reviewer #2:
"My criticism of the paper is that the multi-environmental model is presented very much at face value. The assumptions and construction seem very logical but the choice and constraint of the parameters is by and large opaque. In particular the relationship between the storage component of the multi-environmental model and the Galbraith and Martiny parameterization seems interesting and important but is not really discussed. How important is the storage term in controlling the overall response of the multi-environmental model? It is not at all clear from the manuscript. I feel that some clarification and discussion along these lines is important for the reader."

Best regards, Katja Fennel

Dear Authors,

While I feel that your manuscript has improved by addressing the previous reviewers comments, the third reviewer has raised a few additional points, mostly concerning the presentation that I would like you to consider.

Best regards,
