From Polar Day to Polar Night: A Comprehensive Sun and Star Photometer Study of Trends in Arctic Aerosol Properties in Ny-Ålesund, Svalbard

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The authors explored the Arctic aerosol properties by using Sun and Star Photometer, which is an innovative research work for this Arctic region, however, overall, the entire manuscript is too verbose to read, lacking conciseness and key points.

There are still some issues that exist:

(1) Since a traditional Sun Photometer is used, it is recommended to simplify the relative introduction to the calibration algorithm and cloud screening, and so on.

(2) Why to reconstruct AOD? The proposed reconstruction method is required to be illustrated in detail.

(3)P719, how to evaluate the reconstruction results? What evaluation criteria are adopted in the analysis? For the AOD in March and April, are the results good, why?

(4) Is it reasonable to use Fourier transform to discuss the periodicity of events? How was the autocorrelation coefficient of Figure 14 obtained to be > 0.47? and How to obtain the correlation coefficient of -1,1 on P565 ?

(5) in Figure 15, How to obtain periodic result analysis, foe low frequency and high frequency?

(6) What are the criteria for determining large particles in the analysis of The Arctic Haze phenomenon?

We deeply thank you again for your constructive comments on our manuscript. Please find our answers under each of your comments in red. With your help, the manuscript improved a lot. We are very thankful, that you invested so much time in the review process

We agree, that the measurement gaps are critical for the FFT-analysis and have therefore removed this entire part in the manuscript.
