As demand for the rainmaking project has increased over the years, in 1975 the Artificial Rainmaking Research and Development Project was upgraded to be the Office of Rainmaking Operations under the supervision of the Office of the Permanent Secretary for Agriculture and Cooperatives. Later, the workload increased, and to provide greater flexibility, the Cabinet in 1992 approved the merging of the Office of Rainmaking Operations and the Agricultural Aviation Division into the Bureau of Royal Rainmaking and Agricultural Aviation under the Office of the Permanent Secretary for Agriculture and Cooperatives.
