Quantitative Remote Sensing of Sulfur Dioxide Emissions from Industrial Plants Using Passive Fourier Transform Infrared (FTIR) Spectroscopy
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis is a well-written manuscript with very good use of the English language. It is based on an experimental study that was recently published. In the present manuscript, the atmospheric dispersion of the SO2 plume was modeled using source parameters and meteorological data to estimate emission rates from the chimney.
The manuscript can be published with a few minor revisions:
Page 4 above equation 3: ...where θ, Ï•– the angle of location and azimuth relative to the observation point... Please draw these also in Figure 1 and use azimuth and elevation (not location) –angle
The figures (e.g. Fig.6) show integrated SO2 concentrations (in mg/m3). How do these compare to the minimal detectable path-integrated SO2 concentration of the FTIR instrument?

Reviewer 2 Report
Comments and Suggestions for AuthorsThe research covers an area that is already known, a lot of papers written by specialists (physics especially) are dealing with this applied idea of using passive Fourier Transform Infrared spectroscopy for the remote detection and quantitative analysis of SO2 emissions from a plant chimney, either belonging to the energy sector, or metallurgical one, in general industrial stacks with gaseous emissions. SO2 is no longer a big problem , as in developed countries SO2 emissions are reduced, by proper primary or secondary technologies (State of art-best available technologies BAT).
I can see an application of your study for controlling-meaning remote controlling. But this must be stressed by you
For Russia the controlling of the problem unfortunately could be useful, as the reduction of emission is not applied in most plants.
I would recommend to change the abstract, making additional development of the use of the proposed technique. And include the novelty- what could spark the interest of the readers.
Adding also at least 5-10 articles (new) are necessary. The very old literature position-please take it out!
The Pasquill-Briggs model used describes the distribution of pollutants in the atmosphere as a
Gaussian distribution, and is considered in literature the most simple dispersion modelling.
Also the number of experiments analyzed are totally not acceptable on my opinion.
I could not see any comment about the climate conditions. Only mathematical relation could confuse from the direct result
Give an international importance of your research, generalize it, based or much more and longer experiments/episodes.

Reviewer 2 Report
Comments and Suggestions for AuthorsHy, dear authors
IT îs not to beleave that You claim to be the first tuning this specific methodology.
Literature as You already indicate starts from the years 1980
For me it îs nothing spectacular presented in the research, starting with the application on SO2
I would warmly recommend a generalizat Ion of the procedure You developed

Round 3
Reviewer 2 Report
Comments and Suggestions for AuthorsHy, unfortunatelly the answers even quite good were not correspondently introduced in the propoer place in the text
I recommend to add a system allowing the alarming when the proposed systm/method depicts
For me it is not a method that is applicabel in practice, taking into account the highteck existing.
