GENERAL COMMENTS
The manuscript has been very carefully revised according to the suggestions of the both referees, and it has been significantly improved: It is now well focused, reads fluently and has all the necessary details for understanding how the different phases of the work were conducted.
I have no suggestions for corrections, despite the technical corrections listed below, and am pleased to recommend this work for publication in Biogeosciences.
TECHNICAL CORRECTIONS
Page 2, line 6: The verb is missing in ‘…boreal forests are known to significant stocks of organic N…’
Page 2, line 26: Add comma after ‘forest sites’
Page 3, lines 27-30: Complicated sentence, consider revising. Please check also the spelling of the words ‘aerenchyma’ and ‘potential’.
Page 4, line 25: Space missing after the full stop.
Page 6, line 20: Comma is not needed after the parenthesis.
Page 13, line 16: In my opinion, a comma would be a more appropriate separator between the sentences than a full stop.
Page 14, line 8: Letter t missing in Turetsky.
Page 15, line 4: The full word methane should be used instead of the chemical formula in the beginning of the sentence.
Page 15, line 10: An extra full stop in the end.
Page 15, line 19: Please check the correct quoting of Marushchak et al., 2011. The paper do not report large N2O fluxes at permafrost thaw, but from bare peat on peatlands currently elevated by permafrost, where erosion and frost action keep the surfaces bare of vegetation.
References: Please check the use of subscript/superscript letters throughout the reference list!
Page 18, line 5 & Page 19, line 20: The links seem to be to the supplementary information, is this intentional?
Page 19, line 27: A typing error in the name of the last author.
Page 20, lines 12-14: Unnecessary capital letters.
Page 21, lines 14-15: The formatting of the author names differs from the other references.
Page 22, line 1: The author surnames are Tan and Zhuang, please correct the reference.

Short summary

Release of greenhouse gases from northern soils contributes significantly to the global atmosphere and plays an important role in regulating climate. This study, based in N. Finland, aimed to measure and understand release of CH₄ and N₂O, and using satellite imagery, upscale our results to a 2 × 2 km area. Wetlands released large amounts of CH₄, with emissions linked to temperature and the presence of Sphagnum; landscape emissions were 2.05 mg C m⁻² hr⁻¹. N₂O fluxes were consistently near-zero.
