Suggestions for revision or reasons for rejection

The changes in the title of the manuscript are partially satisfactory with respect to some concerns raised by previous reviewers. The work now right presents itself as a "first evaluation" of an experiment whose validity must be deeply verified. However, the Abstract should be rewritten in a clearer, more concise way and without repetition.

The various additions made partially fill the gaps in the initial version of the manuscript. However, some steps are treated rather roughly. I am referring in particular to the experimentation done in a semi-terrain environment (garage) and to the problems relating to the various physical variables (wind, humidity, temperatures, vibrations, ...) that may critically affect the experiment itself. I believe that the work made by the authors deserves to be published but after further revisions and technical corrections, and as a "Technical Report". However, the authors are advised to define the next steps for the full validation of the experiment.

I point out that the additional sentence "without significant variations in the measured gravity by the AGQ" (as response to a comment of the reviewer 1) does not appear in the revised text (cf. p. 19, line 2), and this is not the only case. In the amended text, I did not find even the sentence: "In future experiments, the potential influence of strong winds needs to be assessed. Due to the very recent delivery of the instrument, displacements between observatory locations and system mounting and unmounting cycles have not been as frequent and need to be repeated". Note that the last sentence is part of the response to a comment from the first reviewer and should fill some serious experimental gaps.

Short summary

Gravimetry studies the variations of the Earth’s gravity field which can be linked to mass changes studied in various disciplines of the Earth sciences. The gravitational attraction of the Earth is measured with gravimeters. Quantum gravimeters allow for continuous, high-frequency absolute gravity monitoring while remaining user-friendly and transportable. We assess the capacity of the AQG#B01, developed by Muquans, as a field gravimeter for hydrogeophysical applications.
