Reviewer 3 Report
The authors focused on the evaluation and calibration of the remotely sensed winds from the HY-2B/C/D scatterometer in tropical cyclones. Since the underestimation of high wind speed occurs in the HY-2B/C/D wind speed products, the authors use several machine learning algorithms to improve this underestimation. It is found that the revised high winds are in good agreement with the results from SFMR (Stepped Frequency Microwave Radiometer). This is a generally well-written manuscript with interesting findings. However, it is suggested that the manuscript be accepted for publication with a major revision (see the comments below for the major revision)
Major comments:
1. The authors show us many statistical results to support their conclusions. However, no horizontal distributions of surface winds in a TC from different datasets are shown in this manuscript. The authors should add some figures to show the surface wind speed of a typical TC, and discuss if the revised wind can better represent TC structures such as asymmetric structures associated with vertical wind shear, the radius of maximum winds, and TC size. The discussions can follow some previous studies (Wang et al. 2012; Wu et al. 2015).
2. Did the authors compare the revised wind from the HY-2B/C/D with observations (data from buoy stations)?
3. The authors used the TC centers and the RMW information to select the needed dataset, so where are the data from? JTWC, JMA, or CMA?
