Dear Yaqiong,

your revised manuscript has now been seen by two referees again. The first is satisfied with your revisions, whereas the second raises a small list of issues that should be explained in more detail. I think that list of recommendations should be easy enough to address and I look forward to your revised manuscript, addressing these minor issues.

Cheers
Christoph Müller

Dear Yaqiong,

thanks for the revisions. Before accepting it for publication, I feel that your answers to the reviewer comments should also be reflected by changes in the manuscript.
* You have adequately responded to general comment 3 on the origin of the equations, but when reading the manuscript this is still not entirely clear. Please add the information of your response also to the manuscript in adequate form "eq 1-3 are taken directly from Streck; eq 4-8 are from Bergjor, 9-10 are from Vico and 11-12 are our own empirical functions" or similar.
* similarly, I would like to see that your answer to the energy balance closure problem (comment on L505) can be found in the manuscript as certainly also other readers will have that question
* and finally also the point that you are only comparing to data from USDA non-irrigated winter wheat yield observations is not clear in the manuscript but clearly should be included there.

Thanks!
Christoph

Thanks for the swift response and for publishing with GMD!

Cheers
Christoph
