1. Line 18:“altitude range of 500–5500 m (at a launch angle of 70°). ”Is this altituderange obtained through actual measurement or calculation?

Reply：The temporally controllable rocket is capable of initiating seeding within 2 s to 26 s and can conduct operations for layering, arbitrary altitude and fractional-dose seeding within the altitude range of 500–5500 m (at a launch angle of 70°，calculated based on the flight trajectory of rockets).

1. Line 145:“The rocket begins timing from the moment of liftoff. ”should be liftoff the launching rack.

Reply：The rocket begins timing from the moment of liftoff the launching rack.

1. Table 2: Please explain the differences between the two different rockets.

Reply：Add a paragraph on line 239, “The seeding time of the total bullets has been changed from ≥ 27 seconds to 0.8-32 seconds, which reflects the adjustable and controllable ejection height and duration of the temporally controllable spatial-seeding rocket. The load time range of electronic fuses has been changed from 6-17s to 2-26s, expanding the range of new rocket seeding heights. The seeding time interval of electronic fuses has been changed from the original fixed 2.7s to 0.1-26s, which can achieve both continuous and concentrated seeding.”

Reply：Dong Xiaobo provided methods and ideas for the temporally controllable spatial-seeding rocket. The experiments designed by Liu Yongde and Wang Xiaorong. Dong Xiaobo wrote the first draft, which was further revised by Liu Yongde, and Wang Xiaoqing.

1.Line 21:“parameters such as altitude, thickness and operating temperature of target clouds can be obtained through detection, and they can be used to automatically calculate the suitable seeding time, seeding altitude and seeding dose”.Is it calculated automatically by the the launch control system? Reply：parameters such as altitude, thickness and operating temperature of target clouds can be obtained through detection, and they can be used to automatically calculate the suitable seeding time, seeding altitude and seeding dose by the launch control system based on the flight trajectory of rockets. 2.Line 91: Please mark the upper cover, lower cover, bullets in the Fig2. Reply：Figure 2 has been modified as required. 3.Line 108:“Simultaneously, the delay ignition tube in the next set of launch modules is ignited. ”Should be the second set of launch modules is ignited. Reply：Simultaneously, the delay ignition tube in the second set of launch modules is ignited. 4.Please provide a more detailed explanation of the characteristics of line seeding rockets. Reply：Add the more detailed explanation for the line seeding rockes on line 61: “At present, the commonly used line seeding rocket has a seeding time of 15-30 seconds and a maximum launch altitude of 6-8 kilometers. After the rocket is launched, the catalyst burns inside the rocket body and spreads along the direction of the rocket's flight trajectory. After seeding, a long linear silver iodide aerosol band is formed in the air.”
