Revised version, October 2015

Dear Roger Braithwaite,
Both reviewers were very positive and recommended publication of your study. I think you correctly addressed their comments in your on-line responses and in the revised paper. I have thus the pleasure to accept you manuscript for publication in The Cryosphere.
Before uploading the final files, I have a few minor additional comments/suggestions (line numbers are from the revised "clean" file).
In your last email to me, you mentioned that you would like to make some final changes to the figures. If this is the case, I will ask you to send them to me for a quick editorial check before you upload them in the system.

- L260: N ≥ 6 of "record`". "`" should be removed.
- L289: "and the associated 95% confidence interval here has a width of ± 17 m". As expected, the width of the confidence interval actually depend on the position along the X-axis, i.e. uncertainty of the regression line is larger for extreme mass balance values. Thus, could you clarify for what mass balance the ± 17 m value was calculated.
- L408. " there are no glaciers". Here I am not sure about the correct grammar. What about "there is no glacier"?
- L399. "Kurowski mean altitude" (I suggest adding altitude)
- L446. "with the Kurowski error E_0". E_0 not defined. Rather E_mean has defined in Eq. (8). Or did I misunderstood you?
- L551. "TP-ELA and TPW-ELA" have not been defined.
- L707. "Interactivce" -> "Interactive"

Thanks a lot for choosing The Cryosphere to publish your work,
Best regards,
Etienne Berthier
