Abstract. From August 4th to 30th, 2020 and from November 27th to December 25th, 2020, a self-developed radiosonde balloon system was used to observe high-altitude atmospheric optical turbulence at three sites in northwestern China, and an improved model based on the observational data was established. Through comparative analysis of the observational data and the improved model, the distribution characteristics of atmospheric optical turbulence under the combined action of different meteorological parameters and different landform features in different seasons were obtained. The improved model can show the variation of the detailed characteristics of turbulence with the height distribution, and the degree of correlation with the measured values is above 0.82. The improved model can provide a theoretical basis and supporting data for turbulence estimation and forecasting in northwestern China.

Atmospheric optical turbulence has a significant impact on optoelectronic instruments, so the measurement of atmospheric optical turbulence is very important. The evaluation and forecasting of atmospheric optical turbulence can improve the efficiency of photoelectric systems. Long-term observational data in the arid and semi-arid regions of Northwest China show that our research and model improvements are very meaningful.

Based on the observation experiments of atmospheric optical turbulence at three sites on the Qinghai-Tibet Plateau and the Hexi Corridor in northwestern China, the authors obtained the distribution characteristics of atmospheric optical turbulence under different seasons over different underlying surfaces. In particular, they found that the distribution characteristics of atmospheric optical turbulence under the influence of penetrating convection and subtropical jet are different. Based on the HMNSP99 model, an improved local model is proposed. While there are some issues should be addressed. As you mentioned, much work has been carried out by researchers on the parameterization and model forecasting of atmospheric optical turbulence, please reorganize and summarize the lines of 43-54 in introduction section, while not list one by one. Particularly, you should compare their advantage or disadvantage or differences with your present results, and then make an in-depth discussion and give your implications in a discussion section. In addition, the results can not be clearly derived in figure 2, due to busy sub figures, please reorganize figure 2 for readerships. Generally speaking, the manuscript is scientific sound and well written and organized. I recommend to accept it after minor revision.
