Suggestions for revision or reasons for rejection

I think the paper is in quite good shape after the changes made in response to the initial round of comments. Now I have just a couple of recommendations, and a list of incidental language usage corrections.

1. In the response to Referee #1's major comment 1a, there is some information that I did not see in the revised paper. Specifically, the statement: "[P]ossible reasons [for] suspicious DEVG values [could] be power loss [at the] electrical contact[s] and a bug in the DEVG initialization logic, which is related to [an] intermittently added 1-g-bias, where g is the acceleration due to gravity (D. Body, personal communication)." This information would be useful to include in the paper.

2. p. 2, line 20: Rather than saying that the DEVG uncertainties are assumed to be negligible, it would be more informative to quote the actual figures from the AMDAR manual (3 to 4% typically, 10 to 12% in the extreme).

Language corrections

2. p. 1, line 28: "routine, therefore PIREPs" --> "routine; therefore, PIREPs"
3. p. 2, line 6: "metrics are" --> "metrics were"

ED: Publish subject to technical corrections (26 Feb 2020) by Wiebke Frey

Dear Soo-Hyun Kim et al.,

as you can see from the reviewers report, there are a few minor points which I'd like to ask you to consider, see below, before publication of the manuscript.

best wishes,
Wiebke Frey

Short summary

We retrieve the eddy dissipation rate (EDR) from the derived equivalent vertical gust included in the Aircraft Meteorological Data Relay data for more reliable and consistent observations of aviation turbulence globally with the single preferred EDR metric. We convert the DEVG to the EDR using two methods (lognormal mapping scheme and best-fit curve between EDR and DEVG), and the DEVG-derived EDRs are evaluated against in situ EDR data reported by US-operated carriers.
