Climate-Quality Calibration for Low Earth-Orbit Microwave Radiometry^†

Round 1

Reviewer 1 Report

It is a good concept paper, and quite impressive for its ideas, while the only comments for this paper is about the background and motivation, we hope the author can prepare more material for support the overall ideas, or provide more fundementala or experimental calculation, or design shemes for this concept, it should be a good paper for Remote Sensing.

Author Response

Thank you for the positive evaluation.

Some sentences have been added to the first paragraph of section 1 and the first and next-to-last paragraphs of section 2 in order to provide more motivation and background. These are highlighted in yellow in the revised manuscript pdf file.

In section 2, we want readers to understand that there is more than one possible engineering approach to achieve the objectives; for that reason, it does not include details of receiver design, such as a circuit diagram. The paper is still at the stage of a concept, and we have no experimental data to present.

Reviewer 2 Report

There are no special remarks, the paper is short, recommended for publication

Author Response

Thank you for the positive evaluation.

Reviewer 3 Report

The proposed manuscript suggests radiometer design approaches to achieve these Linearity, stability, and traceability of measurement objectives in a microwave calibration-reference instrument.  Multi-year stability is verified by comparing with radio-occultation measurements.
 

The manuscript is an original work and a good concept contribution to the journal. I recommend the manuscript to be published in its current form.
