Reviewer 2 Report
Comments and Suggestions for AuthorsFar ultraviolet detection has important scientific value, and quantifying data is even more challenging. This article introduces the preliminary results of radiance cross comparison between FY3E/TriIPM and TIMED/GUVI, The analysis reveals that the consistency of the OI 135.6 nm and LBH radiation is better at 1700 LT than those at 0500 LT in the Northern and Southern Hemispheres, and the consistency of the LBH radiation is better than those of the OI 135.6 nm in both Hemispheres at 0500 LT and 1700 LT. Moreover, the measures of FY3E/TriIPM and 15 TIMED/GUVI agreement well in summer and winter compare to the equity, especially at 1700 LT. The conclusion has important value, and four suggestions are provided for the authors:
1. Please provide the calibration results and radiance uncertainty analysis of TriIPM in laboratory, which are the basis and prerequisite for quantitative comparison;
2. Please provide information on performance parameters of GUVI and TriIPM, such as spectral response function, field of view angle, response linearity, dark current, stability, radiometric calibration results, measurement uncertainty, etc;
3. It is recommended to provide an analysis of the impact of TriIPM laboratory and in orbit radiometric calibration on the cross comparison results;
4. Please explain the meaning of the spectral responsivity unit: counts/s/R in Figure 1.
