The reviewers considered that the study has potential, but requires further work and could not be published in its initial form. I understand that you have made changes to the manuscript in response to the reviewers' comments. Please upload your revised manuscript for further review.

This paper has now had reviews from 4 different reviewers. Three of those reviewers unfortunately found that the data are not of sufficient quality to support the conclusions, and that the temperature changes reported in the work cannot be clearly linked to EPP. Of course it can be difficult or even impossible to substantially improve the data quality without changing the instrumentation. I wonder if it may be possible to get more confidence in the results by changing the integration window of the spectrometer data, so that instead of starting on an hour or half hour mark, it starts at the start of the event, although this may not be enough of an improvement. However, I think the final conclusions of the work as stated in the last sentence of the abstract could possibly be supported - that the data show no clear temperature change following "normal" EPP events - and I think this could be worth reporting.

All of the reviewers said the work may have potential, and I agree. So I would reconsider this manuscript after substantial changes, in particular reconsidering the interpretation of the data and changing the emphasis of the conclusions.

As you can see from the latest reviews, there are still concerns about the interpretation and discussion of your results, but the reviewers still find that the paper has potential and the analysis is worthy of publication. I realise that this paper has been through many iterations, but I think to be accepted the conclusions need to be softened further. Hopefully the reviewers' comments help in this regard. If you need more time to make changes please let me know.

I think this manuscript is now ready to be published, subject to making the minor corrections suggested by the reviewer. Once you have made those changes I am happy to accept it. Thank you all of your responses and changes over the past year - I hope you agree that it was worth it, and the final paper is much improved as a result.
