Review 2 comments on revised m/s:
MINOR COMMENTS
- Line 68-78: Somewhere in this literature review, you should discuss McCreight et al. (2014), which is of high relevance to the current study (e.g., same study area, also uses Lidar data to examine uncertainty from sparse point measurements).

TECHNICAL COMMENTS/CORRECTIONS
- Line 82: Add “an” before “approach”.
- Lines 202-245: This has become an incredibly long paragraph. Please break into two (or more) paragraphs. It may be natural to begin a new paragraph at “Firstly” (line 218), and then another new paragraph at “Secondly” (line 237).
- Line 245: Replace “Additionally” with “In addition to”. (“Additionally is an adverb and it does not appear to be appropriate in this context).
- Line 508: Add “of” after “case”.
- Supplement, Page 4, Line 2: Replace “tem” with “term”.
