- Calcium Chloride powder (Formula 6) - Calcium Carbide powder (Formula 9)
• From 1981 to 1982
In mid 1981, Calcium Oxide powder (Formula 8) was tested for the “triggering” step. The chemicals used in the Royal Rainmaking operation during this period were the same as those used from 1977 to 1980.
• From 1977 to 1980
In mid 1977, the experiment using a concentrated solution of the mixture of Ammonium Nitrate and Urea was carried out (NH4NO3: Urea : water = 1 : 1 : 2). This solution could drop the temperature to between -5 °C and -7 °C, and was used in the step of “attacking step,” or to force the clouds to rain, and to increase rainfall efficiency. However, the technique of spraying a concentrated solution often created a technical problem. Therefore, Ammonium Nitrate in a form of powder or Formula 19 was tested and yielded successful results. Between 1977 to 1980, the chemicals used by the Royal Rainmaking Project were:
- Sodium Chloride powder or Royal Rain salt flour (Formula 1) - Dry Ice (Formula 3)
- Urea powder/concentrated Urea solution (Formula 4)
- Calcium Chloride powder (Formula 6)
- Calcium Carbide powder (Formula 9)
- Ammonium Nitrate powder or concentrated solution
(Formula 19)
