Authors,

Thank you for your contribution. I find the manuscript to be high quality and to have been revised well in response to the comments from the two referees. I found a few minor technical points that could improve the readability of the manuscript and figures, but otherwise I am happy for the manuscript to proceed to publication. See my comments below.

Congratulations and best regards,

Alex Huffman

Minor technical points:
- The author response about the distance to the Fudan measurement site (23.5 km) is useful information and should be included in the revised manuscript. I suggest adding a sentence (or part of a sentence) with this distance and about the correlation of measurements, as mentioned in your responses to Referee #1.
- The yellow color of the traces in the bottom panels of Figure 3 is a bit hard to see. I suggest revising the figure with a slightly darker shade of the color.
- A similar comment applies to the light green color used for multiple figures (traces, markers, and legends). The color makes it hard to read the legend and equations written in the same color. I suggest changing to a different color or to a slightly different shade of green.
