Exploring a Directional Measurement Method of Three-Dimensional Electric Field Intensity in the Atmosphere

Round 1

Reviewer 1 Report

The manuscript presents a measurement method of three-dimensional electric field intensity in the atmosphere. The method is based on well known roto-translation matrices. The experimental results show a better reconstruction of the electric field components using the proposed method.

Author’s Response to Reviewers’ Comments

 

Dear Editors and Reviewers:

  Thank you for your letter for the Reviewers’ comments concerning our manuscript entitled “Exploring a directional measurement method of three-dimensional electric field intensity in the atmosphere”(ID:Electronics-1847502). Those comments are all valuable and very helps for revising and improved our paper, as well as the important guiding significance to our researches. We have studied comments carefully and have made correction which we hope meet with approval. Revised portion are marked in yellow in the revised manuscript. The responds to the Reviewer’s comments are shown in this file, the Reviewers’comments were mark in red, and the important responds were expressed by Bold Font.

The following are the modifications and responses to the modification suggestions of the three reviewers.

 

(1) Comments and Suggestions for Authors

The manuscript presents a measurement method of three-dimensional electric field intensity in the atmosphere. The method is based on well known roto-translation matrices. The experimental results show a better reconstruction of the electric field components using the proposed method.

 

1. Matrix F in equation (7) must be defined?

Responce: We are very sorry our negligence of the typing error, it should be Matrix E, not Matrix F, so the equation (7) should be expressed as .

 

2. Lines 226 251 253:  “12kV/m” should be written “12 kV/m”

Responce: We are very sorry our negligence of the typing error, The electric field strength should be expressed as 12 kV/m.

 

3. - Line 276: Table1 should be Table2

Responce: We are very sorry our negligence of the typing error, Table should be Table 2.

 

4. Some comment on Table2 should be added: why the measurement of the Y component has the most evident effect on the reduction of the mean and maximum error?

Responce:

We are very sorry our negligence of the typing error, the Table 2 indicates that the revised 3D electric field directional decomposition model reduces the maximum errors of the electric field components in the geographic directions of East-West and North-South from 13.6% and 16.8% to 9.4% and 9.3% compared with the traditional model. Additionally, the average error decreases from 9.1% and 11.7% to 5.5% and 7.0%. In the loading direction of the electric field, i.e., the direction of the geographic plumb, the maximum error of the electric field component intensity decreases from 9.3% to 7.9%, and the average error decreases from 5.3% to 4.5%.

And we are very sorry our negligence of the methods and results of the experiment were not explained in detail. This part is rewriten as the follows.

During the experiment, the electric field direction is on Z Axis, The intensity of electric field component in the X and Y directions is formed by the coupling effect of electric field intensity on Z direction, because of the uncertainty of the coupling effect, the maximum and average error of measurement in X and Y directions are larger than those in Z direction. At the same time, α₀=-0.02199，β₀=0.03625，θ₀=0.01902 were calculated by the proposed model. It is found that β₀=0.03625 is larger than both α₀ and θ₀, there is a large coaxiality error between the geographic north-south direction of the electronic compass and the Y-direction of the electric field sensor, which is is due to the manufacturing process of the measurement system. After correction of the model proposed in this paper, the average error and maximum error of Y component have the most obvious reduction effect.  

 

5. Line 287: “0” should be subscripts

Responce:

We are very sorry our negligence of the typing error, it should be expressed as α₀, β₀, and θ₀ .

6. In the revised pdf file, figure captions are sometimes in different pages respect to figure

Responce:

Thank you for reminding me. I will carefully adjust the PDF format when the manuscript is generated.

Make sure the caption is on the same page as the picture

We tried our best improve the manuscript and made some changes in the manuscript. These changes will not influence the content and framework of the paper. And here we did not list the changes but marked in the revised paper. We appreciate for Editors and Reviewers’ warm work earnestly, and hope the correction will meet the approval.

Once again, thank you very much for your comments and suggestions.

Reviewer 2 Report

This is a well-written paper on reducing the alignment errors occurring when measuring atmospheric electric fields.  The authors propose what appears to be an original solution that allows a significant reduction in these errors.

My primary comment on this manuscript is that the literature review seems quite limited -- there are 8 references and 7 of those are papers that appeared since 2014.  Since this is an old problem, there should be papers, some even classic, going back 100 years that address the measurement issues.  I recommend that the authors provide additional background on this and provide additional history on these measurements.  There are also commercial products that are often used to carry out these measurements and some literature on them would be appropriate.
