Round 1
Reviewer 1 Report
The authors have discussed vicarious calibrations using ground-based targets. "Rochester Institute 94 of Technology’s Tait Preserve test site" is very unique.
"The 177-acre property" is large but seems too small to the spatial resolution for NASA MODIS and JPSS VIIRS. I would suggest the authors in Abstract to specify upper limit of the foot print size your method can be applied.

Thank you for your comments and suggestions. We have edited the manuscript taking these into account. In particular:
"The authors have discussed vicarious calibrations using ground-based targets. "Rochester Institute 94 of Technology’s Tait Preserve test site" is very unique.
"The 177-acre property" is large but seems too small to the spatial resolution for NASA MODIS and JPSS VIIRS. I would suggest the authors in Abstract to specify upper limit of the foot print size your method can be applied. "
We have added a line in the abstract commenting on the scalability of the SPARC Technique. While we had previously noted that a commercial application of the technique currently exists which can serve pixels up to 60 m, we have added that the Tait Preserve could be used for pixels on the order of 10 m, commented on the factors governing pixel scale for a given site, and specifically referenced that it would be possible to accommodate MODIS with a dedicated site and facility of sufficient scale. In fact, we would welcome the opportunity to attempt such a project if the resources and funding could be procured.
We have also made multiple minor language and grammar edits which hopefully improve the clarity of presentation.
Reviewer 2 Report
The authors presented the preliminary results of G-SCALE experiment testing and also discussed the scope of future work.
Author Response
Thank you for reviewing our paper. We note that no edits have been suggested. We have made some minor edits to correct a few misspellings and grammatical errors.
