Dear Prof. Añel,

Thank you very much for your message and for bringing this important issue regarding the GMD Code and Data Policy to our attention. We sincerely apologize for our previous oversight in not providing complete repositories for both the code and data used in our manuscript.

Following your guidance, we have now deposited all the model code and data necessary to reproduce the results presented in the manuscript in open-access repositories:

•    Code repository: https://doi.org/10.5281/zenodo.17293102

•    Input data repository: https://doi.org/10.5281/zenodo.17296305

•    Output dataset repository: https://doi.org/10.5281/zenodo.17083972

We have also revised the Code and Data Availability section of the manuscript accordingly. The updated text to be included in the next submission reads as follows:

The TCKF1D-Var framework source code is openly available at GitHub (https://github.com/smft/TCKF1D-Var) under the GNU Affero General Public License (AGPL). The exact version of the code used to produce the results presented in this study is archived on Zenodo (Zhang, 2025; https://doi.org/10.5281/zenodo.17293102). The input data required by the TCKF1D-Var framework are available on Zenodo (Zhang, 2025a; https://doi.org/10.5281/zenodo.17296305). The TCKF1D-Var thermodynamic and hydrometeor profile dataset generated in this study is also archived on Zenodo (Zhang, 2025b; https://doi.org/10.5281/zenodo.17083973). All datasets are publicly available under the Creative Commons Attribution 4.0 International (CC BY 4.0) license.

We greatly appreciate your attention to this matter and the opportunity to correct our mistake.

Please let us know if any further clarification or adjustment is required.

With best regards,

Dear Reviewer,

We would like to sincerely thank you for your thorough review and constructive feedback on our manuscript entitled “Retrieving Atmospheric Thermodynamic and Hydrometeor Profiles Using a Thermodynamic-Constrained Kalman Filter 1D-Var Framework Based on Ground-based Microwave Radiometer”. We greatly appreciate your positive evaluation of the study’s novelty, methodological soundness, and overall contribution, as well as your valuable suggestions for further improvement.

In response to your Summary statement and General comments, we have carefully revised the manuscript to improve clarity, transparency, and reproducibility. Specifically, we have:

1. Clarified the theoretical justification and numerical implementation of the ratio-based cost function.
2. Expanded the discussion on the mid-tropospheric humidity degradation and provided additional quantitative analysis.
3. Enhanced the data and code availability statement in accordance with GMD’s policy.

Detailed responses to all Specific comments and Technical corrections are provided in the attached file ReplyToReviewer#1-20251106.pdf, where each point has been addressed individually.

We once again express our sincere gratitude for your thoughtful comments and helpful suggestions, which have significantly improved the quality and clarity of our manuscript.
