Suggestions for revision or reasons for rejection

The paper describes a new GW analysis algorithm that is based upon hodograph technique and linear theory. The scientific discussion and description is reasonable clear, but the paper can be improved by some English editing work. In some part of the paper, long sentence without comma makes it slightly difficult to follow. There are also several places in the paper where the definite article "the" are missing. I only list a few examples for the author to consider.
1. On page 5, in the first paragraph of section 4.1. The third sentence "The main reason..." reads a little bit odd. Please consider to revise.
2. Same page in line 29, the author chooses 15 km as the upper limit. Can you justify it? The diurnal tide has the vertical wavelength > 20 km, why not choose 20 km as the upper limit?
3. On page 7, in line 10. "a constant background" is misleading, I think. The background is not constant over time, so I think the author is referring to an instantaneous constant vertical background profile. Please clarify.
4. On page 9, line 25-27. Please clarify why removing waves with vertical wavelength less than half of the wavelength and twice the wavelength can minimize the uncertainty due to the presence of the other waves. BTW, here is one place that is missing "the".
5. On page 10, the first sentence in section 4.6, could be "If, in the previous step, the...".
6. On page 15, in line 3, add "the" in front of "downward propagating waves" and "upward propagating waves". Same for the other places like this.
7. Same page, line 11, "demonstrates that, for these measurements, the vertical...".
8. Same page, line 13, " ... to 70 km, where... the momentum flux, we.."
9. Same page, line 21, "In this paper, we..." line 22, "Most of the steps, if...". Line 23, "... of this work are their..."
10. Page 16, line 5, "consists of".
11. Same page, line 6, ", and subsequent..."
12. Same page, line 18, "analysis technique, which..."
13. Same page, line 26, "... stage of development, our..."
14. Same page, line 27-28, "... under development, as well as, an additional robust algorithm, to pick..."
15. Page 17, in line 2 "GWs".
16. Same page, line 6. Please provide reference for the last statement.

Short summary

One of the major problems of climate and weather modeling is atmospheric gravity waves. All measured meteorological parameters such as winds and temperature reveal superposition of large-scale background field and small-scale features created by waves. We developed an analysis technique that decomposes the measured winds and temperature into single waves, which allows for a detailed description of wave parameters. Application of this technique will improve understanding of atmospheric dynamics.
