Thank you for your comment. Reviewers did identify these limitations and we addressed them by providing details on the methods used in measurement of the two ES. We cautiously applied this valuation to global estimation of ES and provided caveats, as listed in the article itself. We agree, more data on measurements in different seasons will help improve valuation.
