Dear author,

Thank you very much for submitting your revised manuscript. However, please note that with your revised manuscript, you are asked to provide a version in “track change” mode. Without this version, it is quite difficult to analyse exactly what you changed (for example if you really answered V. Eyring's request to use CMIP6 experiment names and abbreviations). Nevertheless, I recommend that your revised manuscript be published with minor revisions given that your changes related to the reviewer's comments were relatively easy to track anyway.

Important comment:
-p.13, l11-13: To answer V. Eyring's request, you wrote “Note that analogous to the CMIP6-endorsed OMIP (Griffies et al., 2016), we request that files containing cell areas for the oceanic (areacello) and atmospheric (areacella) grid are supplied as part of the SIMIP output to allow for the correct weighting of individual grid cells.“ However V. Eyring's request is about providing weights for the regridding from the source native grid to one or two target CMIP6 standard grids (i.e. to provide, for all source cells contributing to the calculation of one target cell value, the weight of each of these source cell in the regridding calculation), not about providing cell areas for weighting of individual grid cells. Please correct.

Minor comments:
-p.20, l11, please add a parenthesis at the end of the line
-p.23, l3, please change “averageing” for “averaging”
-p.2, l16, please change “endorsed” for “CMIP6-endorsed”
-p.2, l19, please change “CMIP6 endorsed “ for “CMIP6-endorsed”

With best regards,
Sophie Valcke
