In order to apply an artificial rainfall by aircraft seeding of liquid carbon dioxide (LCD) for security of water resources, development of desert and prevention of desertification, the authors conducted several experiments. Six successful results were obtained in two years. The successful results of the LCD seeding experiments on February 27, 2012 and March 14, May 28 and December 15, 2013 were represented in this paper. The experiments, except the third one, were carried out during cold period. The third experiment was carried out in a warm period as a first time experiment, however, the result was also successful. The clouds for experiment were mainly convective cloud type but in some cases were also a stratiform cloud. We can get a water of 1 to 5 million tons by 1 experiment by the amount of 5 kg LCD of CO2. In these experiments, usage of LCD, developing cloud area and amount of rain by a short seeding time were small. If more water is needed, we can seed every cloud on time to time continuously. Therefore, we can produce large amount of water, 10-100 million tons. The charter fee of aircraft is high, however, the amount of water reserved is large. So it can pay finally. Then, it is presumed that the LCD technique can be used for security of water resources to agriculture and industries, development of desert, prevention of desertification, and so on. We believe that this technique can spread all over the world.
