Dear authors,
we received two more reviews to your revised manuscript. Following the recommendations from the reviewers I ask you to thoroughly revise you manuscript once more. The last revision could have been more extensive and avoided or removed ambiguities which are still present in the current version. Moreover, both reviewers ask for improvements in the English language, so please seriously consider that.
If you decide to submit a revised version, a final decision will be made on that version whether your manuscript can finally be accepted for TC.
Regards,
Olaf

Dear Virkam and coauthors,
thank you for your revisions. Given the reviewers recommendation and your response I can accept your manuscript for publication in TC. However, I have some comments still (hence techical correction), which you have to take care of before publication (page and line refer to revised version4), please see below.
Regards,
Olaf

p2l15: As the readers don't have the density at hand, it would be nice to give the thickening also in terms of meters of the surface.
p2l21: I find it puzzling that after two sentences the next one already starts with "The summary ...". I suggest to change that to "Overall, ..."
p2l27: I find this too speculative. If you think so, than this would be your hypothesis to test - which is not done in this paper.
p3l21: make sure the URL is correctly broken across linebreaks.
p4l27: Do you have any other reason to believe this, i.e. evidence?
p5l24: Please change the reference to a manuscript in preparation. Either to pers. comm. or something else (e.g. an abstract already presented at EGU is citeable as Geophys. Abstr. Series).
p8l4: I suggest you use M_B for the variable to be consistent with M_{SMB}. MB does not make a good variable, as written now.
p9l14/15: southeast vs northeast: this cannot be right if you look at Fig. 4a. Do you mean northwest?
p9l21: "at the 23 m long core site" change to "at the site of the 23 m long core".
p9l32: vertically along its length: this is tautological. Remove vertical (as you did not drill a horizontal core).
p13l9: T=H/SMB: you do not have a variable SMB, only M_{SMB}. Change.
p14l28: The whole paragraph has to be adapted and the data should be available before proof reading.
whole manuscript: "minus" should either be in math mode (LaTex) or long hyphen (--).
Fig. 1 b: I can't see a green curve, just blue.
Fig. 2: Do not start a sentence with '+', change to "The SMB derived from stake heights is indicated by `+`markers. Insert "in black" after highlighted.
Fig. 3: Insert north arrow (as you talk about cardinal directions in the text). (Polar Stereo is only has one line parallel to north.) Indicate the reference level for the heights, WGS84?
Fig. 4: Insert north arrow.
(a) shows much more than only the SMB from the stakes, also the interpolation.
After (b) please rewrite:
(b) SMB estimated from radar over the past decade, accounting only for the vertical variability of density. White curves show the location of radar profiles. ...
Fig. 6: "are divided into 3 ..." (remove blank between in and to).
add "each" after "(A-F) with 3 polygons".
