Abstract

This manuscript presents the methods and results for creating an operational Sentinel-3(OLCI) and MODIS-derived burned area product created under the Climate Change Initiative and Copernicus Climate Change Service. The algorithm is an adaptation of the MODIS-based FireCCI51 product. The manuscript s organization is logical, but it requires minor proofreading throughout for both grammar and typography (e.g., consistency with units like km2) that goes beyond the scope of peer review. In general, many methods in the paper refer to external works that reduce the transparency of this work. Particularly, the discussion of the validation methods is far too vague to be understood by the reader, especially considering the study does not implement the short sampling units of the work that it cites. Additionally, the lack of discussion of the dataset’s limitations is problematic for a data descriptor manuscript, especially for burned area products that typically demonstrate high omission error rates.
