Dear Victoria Meyer,

I read the comments and suggestions indicated by the reviewers and your responses how you addressed their major and minor concerns in the revised version of bg-2017-547.

The main critics of both anonymous reviewers were mainly focused on the method which were not clearly stated and described in the manuscript. Your response and indicated changes now sufficiently address these concerns raised by both reviewers regarding the calibration and validation of the LCA model and comparing AGB estimations from LCA and MCH based on the same methodology.

The use of emergent crown area from large trees by airborne LiDAR data to estimate forest biomass is an interesting approach with a broad application for biomass inventories of large areas and to monitor selective logging activities in the Amazon. Therefore, considering the indicated changes of the manuscript, bg-2017-547 is acceptable for publication in Biogeosciences after this revision. I am looking forward to see the revised version of bg-2017-547.

Best regards,
Jochen Schongart

Dear Victoria Meyer,

I read your authors' response, the revised version of bg-2017-547 and the supplement. You sufficiently addressed the comments, critics and suggestions indicated by the two reviewers and bg-2017-547 can now be published after some technical corrections listed below.

Thank you for choosing Biogeosciences to publish your fascinating study.

Best regards,

Technical corrections bg-2017-547

Abstract:
L 45: Please add a apace between “1” and “ha”

Introduction:
L. 89: Should be “e.g.”

Material and Methods:
L. 117: Please insert a space between “2000” and “mm”
L. 137: Delete comma after “Fearnside”
L. 146 and 154: Please add a apace between “1” and “m”
L. 164: Please insert space between “LCA” and “(h)”
L. 165/166: Please add space between number and unit (3 times)
L. 198: Please add space between number and percentage

Results:
L. 216: Please indicate a space between number and unit
L. 240 L. 165/166: Please add space between number and unit (2 times)
L. 244: Please add space between number and unit (2 times)
L. 260: The abbreviation for Wood density WD should be either consistently used in the manuscript or avoided. Alternatively many studies use “ρ” to indicate wood density (as you did in the supplements), however it should be clearly defined in the text.
L. 283: Please indicate a space between number and unit
L. 284: Add a space before and after “=”
L. 287: Add a space before and after “=”

Discussion:
L. 313: Should be “e.g.”
L. 322 and 464: Add a comma after et al.
L. 330: Sometime spaces are indicated after “>” or before “%”, in other cases not, please use constantly the same format
L. 362 and 367: Please indicate a space between number and unit

References:
L. 80c “, 2010.”?

Tables and Figures:
Legend of Table 1: Indicates with uppercase letter. Please format the references in the legend and indicate the significance of “WD” and “AGB” in the legend or below the table as the reader can interpret the results without consulting the text of the manuscript. If you indicate “annual rainfall” there is no need to indicate “yr-1”.
Table 1: It would be helpful to indicate the source of rainfall data. Is the annual rainfall in Chocó really 10 meters. I know it rains a lot in this region, but is it such high?
Legend of Table 3: Indicate (WD) after wood density in the legend
Legend of Figure 4: Shouldn´t it be average wood density (WD)?
Legend of Figure 5: Please add space between number and unit

Supplement:
Legend of Figure S2: Please indicate “height” in lowercase letter
L. 18: Te reference should be Feldpausch. Delete comma after “2013”
L. 34 and 126: Please indicate the “-“ symbol after cm as subscripted symbol
Table S1: I suggest to indicate the value of RMSE for Antimary also with two decimals
Table S3: Also here I suggest to indicate two decimals for the values -0.3 (Bias) 0.8 (R2)
Legend of Figure S4: Please insert a space between “1” and “ha” (L. 85)
Legend of Table S4: Please insert a space between “trees” and “≥50” (L. 85)
Figure S5: This figure should be improved as the titles of the x- and y-axes are difficult to read
The listed references should be formatted following the guidelines of Biogeosciences
Please correct:
Chave et al. 2005; Correct the coauthor´s last names (Riéra, Yamakura), substitute the comma after the title by a dot.
Zanne et al. 2009 Please indicate title of the journal, volume and pages
