The data paper Nineteen months of daily weather logging on the U.S. east coast: The WFIP3 event log is an indispensable and important resource to support a very relevant and novel dataset from the WFIP3 field campaign. The WFIP3 field campaign yielded long-term coastal and offshore measurements aimed at advancing the scientific understanding and forecasting of the offshore atmospheric boundary layer. Given its exceptional relevance, the unique dataset of WFIP3 will be used by researchers interested in the atmospheric conditions in the atmospheric boundary layer on the US East Coast; This data paper and the event log will be a first read for those using the data.  

The paper is very well written (I couldn’t find any typos or mistakes), very well structured, and includes the necessary information, references, and links.

Here are a few questions and comments that might improve the data paper:

• Can you briefly explain why ocean quantities were not logged? The paper’s title does include “weather logging”, but since understanding the ocean processes and their influence on the atmosphere were a crucial part of the WFIP3 campaign and ocean processes are listed in Table 1, the reader is left wondering why they were not included in the log. Is there another publication planned that discusses the ocean processes?
• Can you cite the reasons why the particular ramp rates were chosen? Do they align with what has been used in the literature?
• It might be beneficial for a prospective user of the event log and WFIP3 data to see how the event log can be used in practice. For this paper, it could therefore be beneficial to list an example or two in the appendix of how someone might use the event log. For example, pick a research question, demonstrate how a user might use the various columns in the event log or search through the content, and what the benefit of that might be for this particular research question.

The paper is an excellent summary of the daily event log captured during the WFIP3 project. The WFIP3 field campaign is an impressive collection of both atmospheric and oceanographic measurements taken as part of a state of the art investigation of the air-sea interactions and mesoscale phenomenon in the offshore waters off of Southern New England. The identification of important meteorological and oceanographic features and the ability of NWP models to accurately predict these features will lead to model improvements that will improve public forecasts for millions of people, as well as allowing for the more smooth integration of the proposed multiple GWs of offshore wind capacity in the region to the grid. 

The text is well organized, provides an adequate description of the purpose of the daily log and methodology employed and criteria used to determine days of interest. Researchers and wind energy professionals will find these logs to be an excellent starting point when investigating the different datasets available and when for identifying periods requiring additional attention. All technical items of the paper look to be in order and well documented.

While not required, the paper could be significantly improved for the reader with some additional examples, perhaps some statistics regarding phenomena which were concurrent? Additional information from the remaining measurements and oceanographic measurements would have been ideal, but I am left to assume that this omission has to do with external factors which have unfortunately closed off public access to the data. There are a few minor suggestions regarding some improvements which could be made for future analysis that would be of added value to the offshore wind community, namely a deeper investigation of very low level jets which can occur at lower altitudes than are being used in the analysis and an increased cut-out wind speed which is more relevant for Offshore US wind projects.
