This paper introduces a quick method to detect the methane isotopologues using Radiative Transfer Models. As described by authors, this is just a first step and the retrieval algorithm needs further development. The authors have also investigated the spectral distribution of the methane, and the potential error sources such as from water vapor and SCIATRAN. Overall, it is a clear and well-organized structure. I would recommend accept after only a few minor corrections listed as follows.
Page 1 Line 40 :
“the feasibility” should be “the feasibility of”
Page 2 Line 18:
“ethane” should be “methane”
Page 3 Line 19-21
The abbreviation “GOSAT21-TANSO-FTS” has been defined at Page 1 Line 43-44. Only define the abbreviation at the first time when it is used in the text.
Page 5 Line 16 :
“has significant pedigree ” should be “has a significant pedigree”
Page 9 Line 14:
Remove the extra Kuze et al
Page 11 Line 41:
“which take three” should be “which takes three”
Page 14 Line 33 :
would to be?
